API Development is an effective way for software to communicate and interact with each other over the internet. It’s a great way for developers to expand the capabilities of a program or systems by creating interfaces and allow data to be shared between different types of technology. With an API, existing systems can connect and more advanced solutions can be made. Hiring an API Developer can enable businesses to streamline processes and enable a much faster integration of existing software solutions.
API Developers are skilled engineers specialized in creating new APIs and maintaining existing ones. They are responsible for developing and troubleshooting current APIs, designing APIs from standards-based web services, maintaining inventory and implementing authorization mechanisms. Additionally, they incorporate different technologies together to create advanced software solutions that integrate cloud systems like Amazon Web Services or MongoDB and APIs with point-and-click platforms, like WordPress or HubSpot.

Conform celor 111,592 recenzii, clienții îi evaluează pe API Developers cu 4.9 din 5 stele.I need a complete software-development partner to turn my web-application idea into a running product. The core objective is to design, build, test, and deploy a modern, browser-based application that is fast, secure, and easy to extend. Here is what I have in mind: • End-to-end build: information architecture, UI/UX wireframes, front-end coding, back-end APIs, database schema, and cloud deployment. • Clean, well-commented source code stored in a Git repository I can access at any time. • Technical stack recommendations—feel free to suggest React, Vue, Angular, Node.js, Django, Laravel, or whatever you believe best meets the brief; I’m open to your expertise. • Responsive design so the app works smoothly on desktop, tablet, and mobile browsers. &bu...
I need an iOS application that mirrors the User Dashboard of my existing website. The focus is tight and well-defined: users must be able to manage their profile (edit personal details, change passwords, upload an avatar, etc.) and receive both push and in-app notifications exactly as they do online. You will get API documentation for authentication, profile endpoints and our notification service, so you can concentrate on a clean Swift / SwiftUI front-end and solid state management. The finished app should run smoothly on the current iOS version and be TestFlight-ready. When you reply, point me to past work that shows similar dashboard or profile-centric apps you have shipped—live links or repos speak louder than long pitches. Deliverables • Complete Xcode project with rea...
I’m putting together a restaurant POS modeled closely on the Petpooja experience, and I need the backbone of the system built right away. Your task is to create clean, well-documented PHP APIs that my mobile and web teams can plug into immediately. Scope of the APIs • Core focus: real-time inventory management—stock levels, item variations, automatic deductions after each sale, low-stock alerts, and simple purchase-order generation. • Seamless sales and transaction hooks so that, when I’m ready, we can extend the same codebase to cover billing, reporting, and customer data without rewriting everything. • Secure authentication, role-based access, and clear JSON responses are mandatory so integration stays painless. • MySQL (or MariaDB) is prefe...
I need a full-cycle build of a School Management System delivered as a dedicated mobile app for both iOS and Android. The solution must include a solid back-end, restful APIs, and a well-structured database so that the Admin, Teacher, and Student roles each see only what they should. A classic username-and-password flow is enough for the first release, but it must be implemented securely with proper session handling and encryption in place. Core modules I expect from day one are fee tracking, attendance, timetable, examination results, push notifications, and printable reports. Everything should be responsive to different screen sizes, optimised for low-bandwidth scenarios, and ready for future additions such as two-factor login or parent access without major refactoring. Deliverables ...
My C#-based desktop trading front end now needs a direct, real-time link to Sterling Trader Pro. The goal is full API integration that goes beyond a simple data feed: live quotes and depth, every order type Sterling supports, position & risk updates, plus a back-testing harness on the same codebase so strategies can run historically before they trade live. The current application is stable and well-structured; what is missing is the Sterling layer—authentication, session management, event handling, and the conversion of our existing order objects to Sterling’s message format. All work must remain in C# and respect Sterling’s API guidelines. Deliverables • Connection module that authenticates and maintains a persistent Sterling session • Real-time market ...
I need a developer who can architect and build a bespoke content-management system that lets an Admin securely log in, add or update product records, and publish them to a responsive front-end. Although only the Admin role will use the interface at launch, the permission model must already support limited, section-based access so I can introduce Editors or other roles later without code rewrites. Core features I expect from day one include: • Secure authentication, password hashing, and session handling • Intuitive dashboard with product listing, search, filters, and bulk actions • CRUD screens for products, categories, and static pages, each with SEO fields • Drag-and-drop or multiselect image/file uploads, stored efficiently • Modular user/role layer rea...
I’m racing against a tight deadline and need a dedicated backend developer who can dive straight into an existing production code-base and elevate it without breaking what already works. The current system is live; I’ll share full repository access, architecture diagrams, and a short feature backlog as soon as we kick off. Stack flexibility is important to me—whether you are most comfortable in Node.js, Python/Django, or Java/Spring, the goal is to improve reliability, speed, and maintainability. Here’s what I need from you right away: • Rapid familiarisation with the current architecture, followed by a concise assessment of performance bottlenecks and fragile areas. • Implementation of new endpoints and business logic, keeping coding standards high a...

I am looking for an experienced developer/team to build an MVP civic issue reporting platform for a beta launch in Kanyakumari District, Tamil Nadu, India. The long-term vision is to expand the platform across Tamil Nadu and eventually Pan-India, so the backend and database architecture should be scalable. The platform will allow citizens to report genuine public/civic issues such as potholes, garbage, drainage, water problems, streetlights and other local infrastructure issues. This will initially operate as an independent citizen platform, not an official government application. Core Citizen Features The first version should include: * Simple mobile-friendly interface * Tamil + English * Citizen registration/login * Report an issue * Upload photo/video * Automatic GPS/location capt...
I manage several property listings and, every day, messages arrive in Spanish across Text messages, WhatsApp, Facebook Messenger and Google Voice. I need a single AI-driven solution that can automatically pull each incoming message, translate it to English, understand whether the sender is asking about an available property, a booking detail, or a maintenance issue, and then craft a reply that feels helpful and human. For the reply style, I want a mix of both preset templates (e.g., directions to the property, check-in times, basic troubleshooting) and dynamic, context-aware wording that adjusts to the exact question or concern. The system should log all conversations, flag anything it cannot classify confidently, and let me jump in manually when needed. Please build or integrate with th...
My AI-generated CRM is 90 % there, but a mix of functional, interface, and performance glitches keep the core experience from feeling complete. Automations stall, nurture sequences stop midway, and the cross-selling module never fires. I need a developer who can: • Trace and squash the current functional, UI, and speed issues across the entire codebase. • Finish and hard-test the automation engine so every trigger, timer, and conditional fires reliably. • Build out the full follow-up nurture flow—email/SMS templates are ready, they just need proper sequencing and fail-safe logic. • Activate the cross-selling feature set so related-product offers surface at the right moments. Acceptance will be a fully working CRM where: 1. All existing bugs are clo...
### Telegram Member Extraction & Migration I am a member of a Telegram channel with 30,000+ members. The channel appears to have around 3,000 active users who regularly generate views and engagement. I am looking for an experienced Telegram API/MTProto developer to investigate whether it is technically possible to: * Extract or enumerate the channel's member/user list, despite the member list not being visible to regular members; * Identify active or engaged users where technically possible; * Collect available public user information such as Telegram user IDs, usernames, etc.; * Determine what information can be accessed through Telegram's API when using an account that is a member but not an administrator; * Explore options for transferring, inviting, or attracting these...
I have an existing WhatsApp group whose entire membership I need copied into a fresh group. The task is purely about replicating the member list—no chat history or custom settings have to come across—so the solution can stay lean and compliant with WhatsApp limits. The current head-count is well over 100, therefore I’m looking for an automated method (API integration, approved third-party tool, or a lightweight script) that can: • Pull every existing member ID from the source group • Add them seamlessly to the new group without triggering spam flags • Provide a simple way for me to repeat the process in the future if the roster changes Please build in any required rate-limiting or invitation workflows so we respect WhatsApp’s policies. On deliv...

I need a skilled web developer who can take a concept for a new website, app, or full-scale platform and turn it into a production-ready product. The scope is broad: it may be a business or corporate site, an e-commerce storefront, a booking system, or an entirely custom web application, but the common thread is that the finished build must be fast, responsive, scalable, and easy to maintain. Here is what I’m looking for in practical terms: • End-to-end development — planning, UI/UX, front-end and back-end code, testing, deployment, and post-launch support. • Modern tech stack familiarity. If you regularly work with React, Vue, Angular, Node.js, Django, Laravel, Rails, PostgreSQL/MySQL, MongoDB, AWS, Docker, REST or GraphQL APIs, you’ll feel at home here. ...
I am looking for an experienced full-stack developer to build a simple, modern and mobile-friendly classified marketplace. The platform will allow individuals and businesses to list new or preloved items for sale. Buyers can purchase items in three ways: 1. Fixed Cash Price – Seller sets a price and buyer purchases. 2. Make an Offer – Buyer submits an offer; seller can accept, reject or counter. 3. Auction/Bidding – Seller sets a starting price and buyers compete by placing bids. Key features: * Simple user registration and profiles * Verified user profiles with verification badges * Post listings with photos, descriptions, price and location * Categories and search * Filters by price, location, condition and selling method * Buy Now, Make Offer and Bidding functional...

I already have RPR’s Broker AVM script and token working when I hard-code a property address, but I need a small JavaScript tweak so site visitors can type any address and instantly see the valuation. Here’s the flow I’m after: • An address field sits right inside the existing widget code—no new layout blocks; it should feel native to the page that already hosts my contact forms, listings, and search tools. • On submit, the script captures the typed address, swaps it into the widget’s Query parameter, and calls the RPR service. • The returned valuation opens in a clean, responsive pop-up modal (desktop and mobile) and stays on the same page. • Everything must run inside Sierra Interactive’s Shared Widget / JavaScript environme...
I am looking for an experienced developer or development team to help build a vehicle transport load board and transportation marketplace, starting with the Canadian car-hauling industry. The concept, business model, workflow, core features and initial visual prototype are already defined, and we are now ready to move into MVP development. Unlike traditional bidding platforms, our model is based on fixed-price loads: a dealer posts a vehicle or load at a set price, a carrier can accept it instantly, and the assigned driver manages pickup, VIN verification, vehicle inspection, photos, signatures, GPS tracking, delivery inspection and eBOL through the platform. We want to build iOS, Android and web/admin together on one shared backend, with one mobile app that provides different interfaces f...

I need a web-based inventory system that lets me see, in real time, what I have on hand, what has been sold, and exactly how each sale affects my bottom line. Every stock-keeping unit may be purchased or produced in lots, so the system must allow me to group items by lot, trace their movement, and reconcile quantities automatically. As items leave the warehouse, I want automatic profit-and-loss calculations that factor in cost per lot, selling price, fees, and any manual adjustments I make. Day-to-day, my staff will also use this platform as a lightweight task manager: assigning picking, packing, restocking, and counting duties with deadlines and status updates tied back to the relevant stock items. A clear dashboard that shows outstanding tasks alongside key inventory and financial metri...
I’m putting together a cross-platform billing and inventory SaaS that must run smoothly on the web (React) and mobile (Flutter). The core stack is already chosen: a Django backend with a PostgreSQL database, all deployed on AWS. Key functional blocks you’ll build and wire up: • Subscription engine – monthly recurring plans driven by Razorpay Subscriptions API, with optional Stripe fallback, automatic invoicing, proration, and dunning logic. • GST-compliant invoice management – create, edit, email, and share invoices; integrate with the GSTN e-invoicing APIs for real-time IRN and QR code generation. • Inventory & batch tracking – receive stock, monitor quantities, lot/expiry dates, and link sales orders to inventory reductions. &bul...
I am looking for a Senior Backend Software Engineer to help design and build a scalable, production-grade Agentic Data Platform. The project focuses on building backend infrastructure for LLM-enabled data ingestion, enrichment, processing, and discovery across large and complex datasets.

I’m looking for a complete marketplace listing solution built with PHP (latest stable version) and MySQL on the back-end, paired with a native Android app. The web portal should let me manage three distinct roles—Admin, Seller, and Buyer—each with the appropriate dashboards and permissions. Attached Pdf Flie Please Review & Share Your Work Link Listing Market Place link Android App ink Key points I need covered: • Web portal: clean UI for adding, editing, and browsing listings, plus the usual order flow and reports an admin would expect. • Role management: separate logins and capabilities for Admin, Seller, and Buyer, all controllable from the admin panel. • Android app: native code (Java or Kotlin) that mirrors the core buyer experience, supp...
We run a workflow-automation SaaS that lets customers build event-driven processes, route approvals, and call external services. The stack is Java 17, Spring Boot, PostgreSQL, Celery, Redis, Docker and AWS, all delivered in a fully multi-tenant environment. The immediate goal is to harden security and drive horizontal scalability without slowing feature delivery. That means: • Strengthening authentication, authorization and tenant-isolation layers • Stress-testing and tuning PostgreSQL schemas, indexes and queries for millions of tenant rows • Refining REST/JSON APIs so third-party services can plug in cleanly, with versioning and clear contracts • Profiling Spring Boot services, Celery workers and Redis caching to remove bottlenecks, then containerising improve...
I need a complete, end-to-end system that lets my car-rental dealership manage short-term loans, collect signed consent, and automatically track every toll a borrower racks up while driving in or outside Sydney. Here is the workflow I must see in production: 1. The dealer logs in, checks live vehicle availability, and emails a consent form from the dashboard. 2. The customer opens that form on web or mobile, e-signs, uploads their licence photo, and submits. 3. Once I approve, the keys change hands and the trip begins. 4. GPS hardware in each of my five cars streams location data; any time the vehicle passes through a toll point, the system calls the official Transport for NSW eToll API, records the charge, and assigns it to that customer’s booking. 5. Back in the dashboard...
I need a single, streamlined WhatsApp-based admin chat that serves two purposes at once: handling customer order inquiries and giving my internal team a real-time messaging space. Scope • Set up or connect to the WhatsApp Business API (Cloud API, Twilio, or a similar approved gateway). • Build or configure an admin dashboard where agents can: – Respond to customer order questions from one unified inbox. – Switch seamlessly to an internal channel for real-time team discussions. • Ensure message routing clearly distinguishes external chats from internal threads. • Include search and simple tagging so agents can locate past order conversations quickly. • Provide basic onboarding documentation so new staff can get started without extra trai...

I need a production-ready shopping app built from the ground up, covering mobile front-end, back-end services, and a web-based admin panel. Security & Sign-in Users will create accounts with the classic email/password flow. All traffic must travel over SSL, and stored credentials should be hashed and salted so the authentication layer passes a penetration test. Shopping Experience The interface has to feel effortless: smooth screen transitions, category browsing, and a fast, typo-tolerant product search. I’m expecting native performance on both iOS and Android, but I’m open to React Native or Flutter if you can still hit that standard. Payments Checkout must launch with PayPal, Stripe, and Square fully integrated. Each gateway should return clear success/failure ca...
I am planning to launch an end-to-end ecommerce solution that can stand shoulder-to-shoulder with Amazon, Flipkart, Meesho, Snapdeal and Myntra. The build must ship simultaneously on iOS and Android, delivering a smooth, modern shopping experience that scales to a large, varied product catalogue. Core functionality I need from day one includes: • User account management (secure sign-up, social login, profile, wish-lists) • Payment gateway integration with all the standard cards and UPI/wallet providers for the Indian market • Product reviews with ratings, photos and a simple moderation flow If you have already built commerce apps, please share live links or store screenshots that prove it—your past work will be my primary evaluation criterion. At hand-ov...
I'm looking for a senior developer with hands-on experience defeating Arkose Labs FunCaptcha (specifically the newer game variants such as hopscotch_highsec / hopscotchv3) in a headless / API-based pipeline. ▎ ▎ I already have a working Node.js codebase that: ▎ - Mints Arkose tokens via a real-Chrome TLS client (bogdanfinn) ▎ - Rotates residential proxies + BDA fingerprints per attempt ▎ - Uses commercial classifiers (YesCaptcha, OmoCaptcha, ) ▎ ▎ The pipeline reaches the challenge-submit step consistently, but the classifiers we use are giving low-accuracy answers on the newer navigation-style variants, so we're getting solved:false on the final wave. ▎ ▎ What I need help with: ▎ - Diagnosing whether the failure is truly answer-quality vs a deeper trust/suppression issue ▎ - Imp...

I’m creating a companion-on-demand service that lets users book an “online rental boyfriend” quickly and discreetly, and I need a complete product that works seamlessly as both a website and a mobile app (iOS and Android). The heart of the product is a smooth booking flow: visitors browse available companions, select a time slot, confirm the rate, and pay securely in just a few taps. A real-time availability calendar, automated confirmations, and push/email reminders all need to be in place from day one so customers feel confident their booking is locked in. While the booking system is the must-have feature, I’d like the codebase and database schema structured so that user profiles and private messaging can be switched on later without a full rewrite. Clean modula...
I’m putting together a straightforward location-tracking system for loads of non-perishable goods that move through warehouses, trucks, and rail cars. The core requirement is real-time position updates from departure to storage, with automatic alerts if a device signals potential theft. The hardware can be either single-use—so the receiver never has to return or recharge the tag—or a reusable unit that we can redeploy after each trip. I’ll need your help scoping both variants and producing an estimated cost per device for each. What I expect from you • A concise technical proposal outlining the recommended tracker form factor, network technology (e.g., GSM, LTE-M, NB-IoT, LoRaWAN), and back-end platform or API you plan to leverage. • A table or brie...

I have an enterprise-grade, multi-vendor SaaS marketplace that is feature-complete on paper but still awaiting a green light for production. Before we release, I need an experienced Technical Project Manager or Technical Product Manager to give the entire platform a hard, independent review and drive it all the way to an unequivocal “ready” or “not ready”. Scope you will own • Perform a line-by-line review of the build against the existing SRS, challenging developers whenever implementation drifts from spec. • Orchestrate milestone planning and daily follow-ups with the current dev team so fixes, retests and regressions stay on schedule. • Design and execute full UAT: test every workflow, log defects in detail, and verify fixes. The goal is sim...
I want a complete fitness tracking app built around my personal-trainer brand. The core of the project is to give each client a private login that opens a personalised dashboard where they can: • watch my step-by-step exercise videos and written how-to guides • read tailored nutritional information • fill out and submit workout-plan forms I create for them • upload their own progress photos and short videos so I can review technique and results An intuitive admin panel is essential so I can add new content, approve uploads, and track every client’s progress without touching code. Smooth UX on both iOS and Android is a priority, and the backend must be secure enough to handle sensitive health data as well as media files. Deliverables I need to see before...

I’m building an online “rental boyfriend” service and need it available on the web as well as native iOS and Android apps. The core experience has to feel instant and personal, so an in-app live chat is the first feature I want working flawlessly. Users should sign up or sign in with their preferred social media account (Facebook, Google, or Apple are all fine), then jump straight into chatting with listed companions. What I already have in mind • A clean, swipe-style catalogue of profiles with photos, short bios, interests and hourly availability. • Real-time chat that supports text, emojis, read receipts and push notifications. • Admin tools that let me verify new “boyfriend” profiles, adjust availability calendars and step in to modera...
Currently, each invoice request requires me to complete several steps. The guest sends me a message or calls me, provides their company details, which I then have to enter manually, locate the relevant reservation, issue the invoice in my invoicing software and send it by email. With seven apartments and a high number of bookings, this results in many additional tasks every month, while manually entering the information creates a risk of errors in the tax identification number, company name or address. My idea is to fully automate this process. The guest scans a QR code placed in the apartment, completes a short form and confirms the information using a link received by email.

I have a complete, clean PostgreSQL database of a football club's entire match history — 120 years, roughly 6,900 matches, with lineups, goals, cards, players, managers, referees and venues. **The data work is finished.** I need a developer to build the website on top of it.
