I’m building an ambitious FitTech platform and need a developer who can own the entire server-side stack. The project’s focus is squarely on backend development, and I’ve settled on Node.js as the core framework. Your job is to architect and implement a clean, scalable API that will power both web and mobile experiences. You’ll decide on the most suitable database strategy, set up authentication and session handling in a secure way, and write modular code that makes future feature additions friction-free. Real-time performance and smooth integration with wearables or third-party fitness services are important goals, so please be comfortable designing for high concurrency and low latency. Automated testing, clear documentation, and Docker-friendly deployment pipel...

I’m building a proof-of-concept that processes banking data with AWS Lambda and serves the resulting artifacts from an S3-hosted site. The core of the job is to design and code a small set of Lambda functions dedicated to data processing, wire them to S3 events, and secure everything with properly scoped IAM roles. What I already have: • An AWS account ready for you to work in. • Sample banking datasets for the PoC. What I need from you: 1. Lambda functions that ingest the banking data dropped into a designated S3 bucket, run the processing logic (Python preferred, open to Node.js), and write the transformed output back to S3. 2. A clean folder structure in the repository plus clear deployment scripts (SAM or Terraform—your choice as long as it’s repeatable). ...

My application already has a solid foundation, but it needs a skilled hand to push it to production-ready quality. The stack is set—React on the frontend, RESTful services on the backend, and MongoDB for persistence. I will share an existing style guide so the UI you craft stays fully aligned with our brand, while still giving you room to suggest micro-interactions and performance tweaks. Here is what I need next: • Build out responsive, accessible React components that follow my design guidelines and render cleanly on mobile and desktop. • Extend the backend with secure, efficient endpoints focused on authentication and user management. You’ll own both the business logic and API integration layers. • Refine MongoDB schemas where necessary, set up indexes, ...

My production site runs on the React JS on the client, a Node.js/Express API, and MongoDB for persistence. After an external audit with another freelancer I now have a clear list of security weaknesses and several functional bugs that escaped earlier testing. Most of the issues sit in server-side logic: exposed endpoints that bypass auth checks, insecure data validation, and some race-condition edge cases that crash certain requests. On the client, a few components render unpredictable states after failed API calls, so error boundaries and tighter state management will need attention as well. I will share the exact findings (code snippets, Postman collections, and a short Loom walkthrough) at project start. All fixes must be applied directly to the production branch via fork-and-PR so I...

I am looking for an experienced full-stack developer to finish, debug, and prepare for production an existing fragrance web application called Scent Layer. This is NOT a project that needs to be built from scratch. The application already exists, the source code is on GitHub, the frontend is deployed and working, the backend is running, and the PostgreSQL database has already been configured. Current technology stack: - React + Vite frontend - Node.js + Express backend - PostgreSQL - Prisma ORM - Anthropic Claude API / AI features - Stripe payments - Email integration - JWT authentication - GitHub - FastComet / cPanel hosting Current status: - Frontend is already live and working. - Backend/API has been deployed. - PostgreSQL database is created and connected. - Prisma database structure i...

I’m ready to retire Firebase and stand up a classic Node.js + MySQL stack behind my existing React front-end. The goal is a like-for-like migration: all calls that currently hit Firebase should instead be served by a new RESTful API built with Express, with data stored in MySQL. Database I already have part of a MySQL schema in production, but several collections live only in Firebase. You’ll need to merge the two worlds—re-use what exists where it makes sense and design fresh tables when the Firebase structure doesn’t map cleanly. I’ll provide the current schema dump and access to the Firebase JSON export so you can plan the mapping. Authentication User sign-in must move from Firebase Auth to running on Node.js. Standard email/password flow is enough f...

I’m assembling a cross-platform solution that links university students to corporate recruiters through three core experiences: • Student profiles that hold rich, searchable content—at launch this means text descriptions and images, with embedded project links and dynamic skill tags. • A job board where students slice results by role type, location, domain and salary. • A Kanban-style ATS for recruiters, mirrored by a real-time status dashboard on the student side. Authentication is social-only for now, using Google OAuth. Please structure the auth layer so additional providers or SSO can drop in later without a refactor. Tech stack expectations Web: React.js or Next.js. Mobile: Flutter or React Native—feature parity with the web version. Backe...

I need production-ready software that proves out the latest frontier-model capabilities from end to end. The work spans everything from designing the data layer to wiring up sleek UIs, then packaging and deploying so that real users can click around and see the model in action. You can reach for the stack that lets you move fastest—Python/Django or FastAPI, Java/Spring Boot, TypeScript/Node.js or , even Rust, C#, or modern C++. Cloud services (AWS, Azure, GCP) and containerisation with Docker/Kubernetes are welcome if they speed delivery; I’m flexible as long as the final result is easy to stand up and maintain. Frontier-model features sit at the heart of each build. Whether it’s natural-language understanding, computer-vision pipelines, data-driven recommendations, or ...

A responsive web application needs to be built end-to-end in Python. The backend will power all business logic, database interactions, and API endpoints, while the frontend must deliver a smooth, modern user experience that consumes those APIs seamlessly. Backend I expect the core to be written in Python using a mainstream framework such as Django or Flask. Key tasks include designing the data models, creating RESTful endpoints, implementing authentication/authorisation, and preparing the project for deployment (Docker or any comparable solution is fine). Frontend Alongside the backend I need the full user interface: page layouts, reusable components, and state management. You are free to choose React, Vue, or another modern JavaScript framework, provided the final result is responsive a...

I’m halfway through a React-based food-delivery platform and need a capable developer—or small team—to bring it across the finish line. The codebase is on Git and already has the basic layout, routing, and component structure in place, but several critical pieces remain: • Frontend polish The interface should feel modern and clean on both desktop and mobile. I have wireframes, a style-guide, and a component library started in Material-UI, yet pages such as the menu grid, cart drawer, and order-tracking view still lack final styling and responsive tweaks. • Core backend features A Node/Express API is live, however user authentication (JWT with refresh tokens) and order management endpoints need to be completed and wired to MongoDB. The data models are s...
