Java Jobs

I need a complete e-commerce application developed in Android Studio. The core of the project is straightforward: an intuitive product catalog that I can easily expand, a smooth shopping-cart flow, and a secure payment-gateway integration so customers can check out without friction. Code must be native Android (Kotlin or Java) and follow current Material guidelines. Please keep the architecture clean (MVVM or similar) and comment your logic so future maintenance is simple. Deliverables • Full Android Studio project with all source files • Debuggable APK and a signed release build • Brief setup/read-me outlining build steps, SDK versions, and how to add new products or payment providers Acceptance will be based on these criteria: products load from a local or r...

I’m expanding my Brazil-based development team and need a proactive, self-driven full-stack engineer who can own features from back end to mobile front end. You’ll be coding daily in Node.js, Java (Spring Boot), React Native, and Angular, with a special emphasis on using AI assistants such as GitHub Copilot or Claude Code to accelerate delivery without sacrificing quality or best practices. Most of our Node.js work powers mobile applications, so familiarity with building and scaling APIs for that environment is essential. You will collaborate through daily video stand-ups, push clean, well-tested code to Git, and help shape architecture decisions as we iterate. What I value: • Solid command of the full listed stack • Demonstrated ability to generate and refine cod...

I need a small, straightforward Android application that opens a pre-loaded textbook and lets the user read it comfortably on any modern phone or tablet. The scope is intentionally light: display the chapters or sections I provide, offer basic navigation (scrolling or swipe between pages), and keep the APK size minimal. I will supply the entire text in an easy-to-parse format—plain text or JSON, whichever fits your workflow. Your job is to lay it out cleanly, respect basic typography, and ensure the app runs smoothly from Android 8.0 (API 26) upward. Please build in Android Studio and stick to Kotlin or Java; no heavyweight third-party libraries unless absolutely necessary. Deliverables • Release-ready APK for quick testing • Full Android Studio project with well-comm...

I’m planning a single hub that lets our users sign in once and reach three core suites—CRM systems, Accounting software, and Project management tools—through a hybrid mobile app and complementary web portal. The entire experience should follow Material Design so the look and feel stay consistent across Android, iOS, and the browser. Core scope • Single sign-on that authenticates across every connected product • Home dashboard that surfaces active subscriptions and licence counts at a glance • Full subscription, licence, plan payment, and renewal workflows • Invoice history tied to each user account • Real-time and in-app notifications • Robust admin console to manage users, plans, and granular access rights • Sales dashboa...

I want to replace the scattered spreadsheets my sales department currently uses with a single end-to-end platform focused first and foremost on payroll and commissions. Core workflow • Pipeline and customer data flow straight into an employee-specific dashboard where every closer can track progress in real time. • The system then applies three commission models—fixed amounts, percentage-based and referral-based—automatically, rolling them into payroll at month-end. • Managers access a visual, multi-level referral tree and a full company admin panel to adjust roles, credit/redemption balances and team targets without touching the codebase. Target environments • Web (for managers and back-office) • Android (for reps in the field) Prefer...

I need a full-stack solution that covers two fully connected areas: Dealership Panel • Vehicle inventory must handle stock tracking, trigger automated low-inventory alerts, and let me export detailed reports. • Bookings, test-drive scheduling, a sales pipeline with customer follow-up, and appraisal workflows all sit in the same dashboard. Public Portal (think ) • Shoppers should be able to filter by price range, vehicle type, and brand/model, then compare results side-by-side. • Each listing shows vehicle history, a rich photo gallery, and transparent pricing. • Visitors can book a test drive online, open a chat with the seller, and run financing simulations without leaving the site. Technical preferences Backend in Java (Spring Boot is ideal) and mo...

I want to commission an end-to-end real-estate platform split into two tightly integrated areas: an Agency Panel and a consumer-facing Public Portal. Agency Panel The back-office must let each agency manage its entire catalogue with fully customisable property fields. Client follow-up tools are essential: I expect a sales pipeline, timeline notes, and reminders that I can filter by stage. Automatic export to external portals such as Idealista and Fotocasa is a must. Calendar-based appointment scheduling, an internal chat between agents and leads, and multi-agency support (each with its own branding, colours and domain) round out the requirement. Public Portal On the front end the visitor experience should mirror sites like Idealista. Core interactions I need are: • property li...

I’m planning a full-feature classifieds platform—web and mobile—modeled after Milanuncios or MercadoLibre. Core modules include dynamic ad publishing with unlimited categories and sub-categories; an advanced search that lets users filter by price range, location, and category and view results on an interactive map; real-time buyer–seller chat; plus a user rating/reputation engine. On the commerce side I need a shopping cart, international payment-gateway checkout, and workflow for orders, shipping, and returns. The back-office must let Administrators, Moderators, and Customer support staff manage users, ads, and editorial content from a single dashboard. Preferred stack: Java for the backend (Spring Boot or similar) and Flutter for the iOS/Android apps, but I&rsqu...

I need a new Android-only application built from the ground up. The app must open with a clean user-authentication flow (email, social, or phone—whichever SDK you feel is fastest to integrate). Once signed in, users will see core content that can be expanded through in-app purchases. Google Play Billing should be wired up end-to-end, including test and production environments, and all purchase events must be validated on the server side. Timely, relevant push notifications are essential. I will provide copy and basic scheduling rules; you will handle Firebase Cloud Messaging integration, topic or token management, and delivery tracking. Deliverables • Full Android Studio project with readable, well-commented Kotlin or Java code • Secure auth module (OAuth2 or Firebase...

I’m starting a green-field product and need someone who is equally comfortable crafting a solid Java/Spring Boot/Hibernate back-end while shaping a clean, responsive Angular front-end. The goal is to deliver an entirely new application, not to patch an old one, so you’ll have room to make architectural decisions and set up best practices from day one. What the stack looks like • Back-end: Java 17, Spring Boot, Hibernate, Gradle/Maven • Database: PostgreSQL (already provisioned) • Front-end: Angular is mandatory; React skills are welcome for any future companion modules. Key pieces of the job • Design the initial domain model, RESTful APIs and security layers. • Build the Angular UI in parallel, wiring it to those endpoints as they solidify...

I have an Android application that is feature-complete but still unpolished. Before I submit it to Google Play I want a fresh set of eyes to run full functional tests, focusing on three areas: • User-interface checks – every screen, button, icon and message should render correctly and be easy to read/use on common phone sizes (Android 8.0 and up). • Input validation – try all the obvious and not-so-obvious inputs, edge cases and empty states to confirm the app never accepts bad data or behaves unpredictably. • Error handling – provoke network drops, wrong credentials and other failure scenarios to be sure the app fails gracefully (clear message, no crash). Please work on at least one real Android device (emulators are fine for extra coverage). I expec...

I need an Android application that lets my internet subscribers manage every aspect of their account from a single, branded interface. After signing in with their phone number and a one-time password, a customer should be able to see plan details, real-time data usage, past invoices, and initiate renewals or upgrades without leaving the app. Integrated support is just as important: a built-in live chat window will connect users to our help-desk team, while a lightweight ticketing system records issues, assigns reference numbers, and pushes status updates via notifications. Both support channels must sync with our existing CRM; I can supply API documentation and test credentials. Clean, modern UI/UX, Kotlin (or Java) code that meets Play Store guidelines, Firebase (or equivalent) OTP ...

I’m looking for someone who can quickly turn my idea for a lightweight social-networking Android app into an installable APK with full source code. The concept is deliberately minimal: users create a basic profile, post short text updates, and like or comment on other posts. No advanced media sharing, payments, or location features—just a clean feed that proves the core interactions work smoothly on recent Android versions. Because my budget is only $10, I need tight focus on essentials: straightforward layouts in XML, clean Kotlin (or Java) code, Firebase or another free backend for real-time data, and clear instructions so I can build and publish the app myself afterward. A simple splash/logo screen and basic auth (email or anonymous sign-in) will be enough. Deliverables ...

I need an Android-only e-commerce application that lets my shop showcase items, accept orders, and instantly send those orders to an in-store printer for fulfilment. The core flow should feel familiar to online shoppers—browse, add to cart, pay—while the back end automatically formats each confirmed order into a clear receipt that prints on our thermal printer the moment the transaction completes. Here’s what I want delivered: • A fully functional APK and clean, well-commented source code (Kotlin or Java in Android Studio). • Simple product management so I can add, edit, and categorise items without touching code. • Secure checkout with the usual options (credit/debit, wallet, or any standard gateway you recommend). • Local or network printing...

I want to package my website, , into a fully functional Android application and have it published on Google Play. The core goal is to mirror the current online experience inside a lightweight, smooth-loading app that passes Play Store review without hiccups. All pages, forms, and interactive elements that work on the site today should behave the same way in the app. If a direct WebView wrapper is enough, great; if you feel a partial native layer would improve speed or push-notification handling, let me know. I’m flexible on the tech stack—Native Android (Java/Kotlin), Flutter, or React Native are all acceptable as long as the final result is stable and future-proof. Deliverables: • Signed, ready-to-publish APK/AAB • Play Console listing fully set up (graphics, descr...

I already have an IPO tracking app in production and now need a dedicated backend service that can fetch allotment results from the 30-plus Indian registrars the moment they go live. The entire service must be written in Node.js, since the rest of my stack is JavaScript based. Core expectations • Connect to every major registrar (KFintech, Link Intime, Bigshare, Cameo, Skyline, etc.) and return real-time allotment status using the usual identifiers—PAN, application number, DP/Client ID, or combination thereof. • Normalise the various HTML, CSV, PDF, and basic API outputs into a single clean JSON response. • Build a set of REST endpoints with simple auth, comprehensive error handling, and logs I can pipe into my existing monitoring. • Provide clear deploym...

I am looking for a developer who can build a full-cycle automation bot that works on the BLS appointment portals serving Morocco for both Spain and Portugal. The bot’s main task is to secure tourist-visa slots while mimicking human behaviour closely enough to avoid the usual 429 / 403 blocks. Core workflow • Auto login, picking the “Visa touristique” option each time. • Intelligent form filler that reads my profile data from a local JSON or database and completes every field. • Calendar handler that searches for a fixed date I specify (with the possibility to switch to random or forced-calendar modes later). • OTP retrieval, photo upload validation and graceful error recovery, all without manual input. • Captcha bypass using a server-si...

I’m kicking off a full-stack project and need an experienced developer who can attack both the front-end and back-end at the same time. The stack is already defined: Node.js (my preferred choice even on the front end), React.js with Redux, and a microservice layer in Java Spring Boot. RESTful APIs, PostgreSQL or MySQL on the relational side, and MongoDB for document storage are all part of the architecture. Speed matters—I’m looking to see working code as soon as possible, so we’ll iterate quickly and ship incremental features rather than wait for a big-bang release. Modern JavaScript (ES6+), async/await patterns, and clean module structure are must-haves; so is writing well-tested, production-ready Java Spring Boot microservices. High-level deliverables: • R...

I’m moving my existing Java-based PDF generation workflow away from iText and need it rebuilt with two tools: • Apache PDFBox for all server-side document creation • Puppeteer for the few HTML-to-PDF screens we already render in the browser The migrated solution must deliver everything the current system does today: rich text, styled tables, embedded images, and full-length PDF reports. Concretely, I expect the new code to: • Preserve every text-formatting rule we rely on, including precise alignment and color control. • Generate tables dynamically, letting me add, remove, or reorder rows/columns on the fly without breaking the layout. • Embed JPEG charts and photos at the exact positions and scales used now. • Produce multi-page reports ...

The goal is to deliver a stand-alone Python desktop application that records classroom or workplace attendance through real-time face recognition. The stack is fixed: Python 3, OpenCV, and the standard Tkinter GUI toolkit. Core flow 1. A compact Tkinter window opens with clearly labelled buttons. The interface must, at a minimum, let a supervisor register new users. 2. During registration the system captures multiple webcam frames per person, automatically saving at least 20 crisp face crops for stronger training data. 3. An LBPH model is trained on those images and stored locally; subsequent launches should reload the latest model without retraining. 4. When recognition mode is active the app checks each detected face against the model and writes a time-stamped entry to a CSV fil...

I’m building a lightweight Android app to keep daily ground-booking records tidy and every rupee traceable. For this first phase I only need the core account system in place so the rest of the product can grow on solid ground. The flow is simple: new users create an account with an email-and-password pair, supplying just a username and their email address. Once inside, they land in the standard user area. An Administrator account gets its own dashboard where I can view bookings, update them, and monitor incoming payments; no charts or calendars yet, just clear tables I can edit. A separate Moderator role also has to exist now so I can later delegate basic oversight tasks without full admin privileges. Security matters, so apply current best practices—hashed passwords, secure ...

I need access to battle-tested enterprise repositories that exceed 50,000 lines of code. The primary goal is to run AI benchmarking, perform deep architecture reviews, and carry out engineering evaluations for technical due-diligence work. Real-world complexity is essential—simple CRUD samples will be declined. Preferred technology foundations include Java, .NET, Python, Node.js, or React, ideally containerised with Docker or orchestrated through Kubernetes and deployed on AWS, Azure, or GCP. Repos hosted on GitHub, GitLab, Bitbucket, or a private Git server are all welcome. Any supplementary assets—such as PRD/BRD documents, Jira tickets, detailed API docs, architecture diagrams, deployment playbooks, or test artefacts—will significantly strengthen your submission and ...

I need a lightweight Android application that lets me manage ground bookings and keep an eye on every rupee that comes in. On the booking side the first (and only) feature I want right now is secure user registration and login. An Administrator role should have its own dashboard so I can view and update bookings; everyone else can simply sign in as a standard user for the moment. Extras such as calendars or push notifications can wait for a later phase. For payments, the app must: • capture each transaction and store an easily searchable history • trigger automatic reminders when a payment is almost due • run the actual processing through a trusted, secure gateway that complies with Android best-practice (Google Pay, Stripe, Razorpay or a comparable SDK) Please build t...

I’m getting ready to release a fresh Android build that adds single-sign-on and other networking changes, and I need a meticulous tester to shake it down on real smartphones before it goes live in Google Play. What you’ll be working with • The app now authenticates through Microsoft Entra ID; parts of the flow also touch Azure and Office 365, so I need each of those sign-in paths verified. • Back-end calls run through AWS and an SAP endpoint, all protected by the same SSO mechanism. • Issue tracking sits in Atlassian Jira, and every finding has to be documented there against the new version tag. • When tests are green, the build must be uploaded to my Play Developer account with release notes that reflect your results. Core tasks 1. Install the s...

I’m ready to bring an online trainer on board who can guide an intermediate audience through real-world applications of Machine Learning, Deep Learning, Natural Language Processing, and some domain-specific AI tool know-how. Sessions will be delivered live, so I need someone who is comfortable explaining concepts clearly, fielding questions on the spot, and showing hands-on demonstrations in popular frameworks (think Python, TensorFlow, PyTorch, scikit-learn, Hugging Face … whatever fits the topic). Because we’d like to launch the program as soon as possible, you should already have slide decks, notebooks, and practical examples you can adapt quickly. A short diagnostic chat with me will finalise the exact schedule, but plan for multiple interactive sessions, each follo...

We are looking for a senior Android developer to urgently investigate and resolve a bug in our Android application. This is not a role for someone who needs heavy supervision, trial-and-error guidance, or long onboarding. We need a developer who can quickly understand an existing codebase, identify the root cause, produce a reliable fix, and communicate clearly throughout the process. The ideal candidate is experienced, practical, fast, and comfortable using modern AI tools to accelerate debugging, code review, test generation, and implementation, while still applying strong engineering judgment. We are not looking for someone who blindly copies AI-generated code. We want someone who knows how to use AI responsibly to deliver faster and more reliable results.

build a Buy-Now-Pay-Later program and need an Android-only locking solution that automatically enforces our repayment terms. Whenever a user misses a scheduled instalment the app must immediately: • trigger a full device lock that prevents normal use until the outstanding balance is cleared; • display a clear, non-dismissible reminder screen guiding the customer to our payment portal. The lock should revert as soon as my server confirms settlement. A lightweight admin console or secure API endpoint is required so my team can push payment-status updates, unlock commands, and view basic device telemetry. Code must be resilient against rooting or factory-reset attempts and comply with Google Play policies for Device Admin / Device Owner apps. Deliverables 1. Android Stu...

This project centres on building a production-ready Utility/Tools Android application written entirely in Flutter. All UI wireframes and detailed user flows are complete; they will be shared once the shortlist is created so you can estimate effort accurately. Core scope The app will rely on a Firebase stack (Auth, Firestore, Cloud Functions, FCM) for data, user management and push notifications. Google Pay is the only payment gateway needed for in-app purchases and subscription handling. I also need AdMob banners and rewarded ads placed in the positions called out in the wireframes. Beyond that, there are two third-party REST APIs that surface real-time data; clean integration with proper error handling and caching is essential. Development expectations – Written in Flutter wit...

I have an anonymised set of internal company emails that must be routed automatically to the correct department—Human Resources, Finance or IT Support. I am looking for an engineer who can take the project from raw data through to a Docker-ised REST service. The workflow I expect is: • Data preparation: strip any residual PII, apply consistent labelling for the three target departments, and document the pipeline so it can be rerun when fresh mail arrives. • Modelling: start with a TF-IDF + SVM baseline, then fine-tune transformer models (BERT or RoBERTa via Hugging Face). Compare approaches and capture precision, recall and F1 for each class. An error analysis explaining common misclassifications is essential. • Deployment: package the best model behind a FastAPI...
