I’m gearing up to launch a truly modular, multi-tenant backend and need a developer who has already walked this road at least once. The goal is not a marketing website but the underlying engine: cleanly separated services, tenant-aware data handling, robust auth, and an architecture that can welcome new feature modules without refactoring the core. You’ll be shaping everything from the database schema to the API layer and background jobs. Tech stack is flexible; the brief questionnaire captured “SaaS” rather than a fixed language, so I’m open to whichever stack—Node.js, Python, or Java—you can justify for long-term maintainability and scale. When you respond, focus on your direct experience building similarly modular or multi-tenant systems: what...

The goal is to turn my paper-prototype trading card game—think Magic: The Gathering—into a full, browser-based experience powered by the MERN stack. I already have card concepts and basic rules; what I need now is the code that makes it all come alive. Core scope • React will drive a responsive UI that lets players browse their collection and assemble decks through an intuitive drag-and-drop builder. • A Node + Express backend, backed by MongoDB, will store user accounts, card data, decks, and match history. • Real-time player-vs-player matches should run over WebSockets ( or similar), handling turn flow, card effects, and game-state sync with minimal latency. • Players gain new cards exclusively by trading with one another, so a secure, peer-to-pee...

My kids’ book-reading app is already live on Google Play, but its current backend has hit its limits. I now need a complete Spring Boot rebuild that is secure, scalable and easy to maintain. Core requirements • Robust user authentication and role-based authorisation • A flexible content management flow that lets me upload, edit and order stories, poems and chapters without touching code • Built-in analytics and reporting so I can track active readers, session length and popular titles • Full chapter management for every book, including draft → publish states What I expect as final deliverables 1. RESTful Spring Boot API with clean, versioned endpoints 2. A responsive admin panel (your choice of React, Angular, or Thymeleaf) tightly coupled t...

I want a complete cryptocurrency trading website built from scratch on the MERN stack—MongoDB, , React.js and Node.js. The goal is to create a single site that bundles the best tools crypto traders normally find scattered across several exchanges. The heart of the project is the trading platform itself. It must handle spot, futures and margin trading and support any other advanced order types we decide to add during development. Order books, depth charts, trade history and account balances all need to update in real time through WebSockets or an equivalent push mechanism; periodic refreshes won’t be acceptable. Front-end work will include a sleek React interface, responsive layouts and intuitive flows for registration, login and secure session handling. On the back end, you&r...

I’m ready to buy a full InDriver-style solution that’s already finished and running. The package must include: • A single Flutter mobile app where passengers create fare offers and drivers send counter-offers. • A connected admin panel for day-to-day oversight. • The complete backend and database, preferably built with Node.js so I can slot it straight into my stack. I’m not looking for custom development—only a turnkey codebase you can hand over immediately. If you have it, please share a short demo or screen recording plus a note on any third-party services it uses. The final handoff should contain the unencrypted source code, build instructions, and any schema or migration files so I can compile, deploy, and test without surprises. First pro...

Our product is live, under active iteration, and we now need an accomplished full-stack engineer to take ownership of the day-to-day care and improvement of the existing React + Node.js codebase. I’m looking for someone with at least five years of hands-on experience who can step into an ongoing development cycle, quickly understand the current architecture, and keep the platform stable while we continue to roll out new features. Your core mandate is maintenance: triaging and fixing bugs, refactoring fragile sections, tightening security, and smoothing performance bottlenecks before they become user-visible issues. I’ll rely on you to review pull requests, guide junior developers, and ensure deployments run cleanly through our CI/CD pipeline. If you have worked with blockchain...

I’m creating a web-based calibration services hub that manufacturing, automotive, pharmaceutical, and other service-oriented teams can all log into from a single URL. The system needs a rock-solid back end, a responsive front end, and the flexibility to store, update, and report on every certificate, audit trail, and service log that users upload. Core features I have in mind: • User management so each stakeholder logs in with the right role, sees only their data, and can track their own calibration schedules. • Document storage with version control for certificates, audit reports, photos, and any supporting files. • Data-rich, detailed dashboards that surface KPIs, calibration due dates, and compliance status at a glance, complete with exportable reports for audi...

I need Google sign-in wired up across my project. The mobile side is built with Expo (managed workflow) and I also have a web front end that talks to a Node.js backend. I’d like you to plug in Firebase Authentication so users can log in with their Google account on both platforms and I receive their basic profile details—display name and email address—nothing more for now. The Expo app already has screens in place; the missing piece is the auth flow and secure hand-off of the Firebase ID token to the Node server, where sessions and any future API calls will be verified. On the web side, a simple Google sign-in button that reuses the same Firebase project will keep things consistent. Please keep the implementation tidy and documented so I can extend it later. I’ll ...

I’m ready to establish a solid digital presence that connects seamlessly with our internal computer system. The public-facing part will be a clean, responsive website that introduces the company and channels visitors toward contact or service pages. Behind the scenes, I need a robust data-management backbone dedicated to secure storage. Here’s what the system must do: • Data management and storage that scales as we grow • Automated backups running on a schedule I can adjust easily • Built-in data analytics tools so I can pull trends and reports without exporting spreadsheets • Granular user-access controls that let me decide who can view, edit, or delete each data set You’re free to suggest the stack, but reliability and maintainability are cr...

My existing n8n automations work, but they feel sluggish and occasionally force me to wait longer than they should. I need an n8n specialist who can improve our current workflows with a clear focus on boosting overall efficiency and speed. You’ll start by reviewing the live flows, profiling each node, and pinpointing where the execution pipeline loses time—whether that’s a poorly-placed wait node, unnecessary loops, or sub-optimal API calls. Once the bottlenecks are clear, I’ll rely on you to refactor the logic, tune concurrency and resource settings, and document the changes so the gains are measurable and repeatable. Deliverables • A brief audit report outlining the key slow points and the optimisation strategy • Updated, fully tested workflow JS...

I’m looking for a full-time front-end engineer based in Gujarat who can own everything we do in React.js and Next.js. You’ll be the point person for new feature work, performance tuning, and day-to-day maintenance of our customer-facing web app. Our backend stack runs on Django with Supabase and Postgres, so you’ll spend most of your time in React/Next but also collaborate closely with the Python team and consume their REST and GraphQL endpoints.

I’m building a ticket-based travel platform and need an experienced NestJS/Node.js developer to own the entire backend. The core of the job is to design and code a robust booking engine, connect it to external services, and expose clean, well-documented REST/GraphQL endpoints for the web and mobile apps that will sit on top. What has to plug in • Payment gateways, travel service providers, and user authentication services all need first-class, fault-tolerant integrations. I already have partner documentation for each service; your job is to wire them up, handle retries/timeouts, and log everything clearly. Booking workflow The platform must perform Real-time availability check before every purchase, send Booking confirmation notifications (email + optional SMS), and support fu...

I need help getting a Node.js-based web app that also exposes an API up and running in my Azure environment. The code is ready; what’s missing is a clean, repeatable deployment that points to our SQLite database and respects the usual production basics—environment variables, HTTPS, logging, and autoscale settings. You’ll work directly in our Azure subscription, set up any required App Service (or container workflow if that proves simpler), wire up the build/release pipeline, and verify the application is reachable from the web as well as through its REST endpoints. I’ll provide repository access and current config files at kickoff; you make the necessary Azure adjustments, push the app live, and document every step so I can reproduce it later or roll back confident...

I need a developer who can build a mobile-first, browser-based application that lets users organise their schedules, log tasks, and track work vs. break time from a clean, intuitive interface. The core of the tool is a calendar that supports simple colour-coded events; beyond that, I want a straightforward task list, a running timer for each task, and automatic push notifications so users never miss an upcoming block of work or a scheduled pause. Because the app must feel seamless on mobile browsers, responsive design and lightweight front-end performance are essential. I’m happy for you to choose the stack—React, Vue, Svelte, or something comparable—as long as it remains maintainable and easy to extend. A modest back end (Node, Firebase, Supabase, etc.) can store user d...

I already have the front-end of an e-commerce site in place; what I’m missing is a robust, well-structured backend written in Node.js with Express and MongoDB. The API must cover three core areas: • User authentication – Secure sign-up / login endpoints, JWT session handling, password hashing, and role-based access control strictly for Admin and Customer accounts. • Product management – Endpoints to add, edit, delete products, assign categories, and adjust inventory quantities automatically after each purchase. Data should be modelled cleanly in MongoDB with appropriate indexes to keep queries fast, especially on category and stock-level fields. • Order processing – Create, read, update order flows that tie into inventory deductions, re...
