You will get Node.js & NestJS Backend API Developer | REST, GraphQL, AWS
Top Rated
Project details
Your backend is the foundation everything else depends on. If it's slow, poorly structured, or breaks under load — your whole product breaks.
I build production-ready Node.js and NestJS backends designed for real traffic, clean architecture, and long-term maintainability.
What's included at $500:
— REST or GraphQL API (up to 10 endpoints)
— JWT / OAuth authentication system
— MongoDB or PostgreSQL database integration
— Input validation, error handling & security best practices
— Deployed to AWS, Vercel, or your preferred platform
— Source code + documentation
Perfect for:
— SaaS platforms needing a scalable backend
— Startups building their first production API
— Existing apps that need backend fixes or refactoring
Need microservices, CI/CD pipelines, or a larger scope? Message me and I'll put together a custom quote.

MERN Stack React Specialist Needed for Small Feature Implementation
I had a great experience working with this developer. They clearly understood the requirements from the start and delivered exactly what was requested within the agreed timeline.
The React implementation was clean, well-structured, and easy to integrate with our existing MERN stack setup. API integration was handled smoothly, and the code quality met professional standards with proper use of hooks and best practices.
Communication was clear and consistent throughout the project, and any small adjustments were handled quickly without issues. For a fixed-price task, the value delivered exceeded expectations.
I would confidently recommend this developer for React or MERN stack work and would be happy to work with them again on future projects.

It was great working with Haseeb. He invested a lot of time and effort into building the app for us. Things got a bit challenging toward the end, but he resolved the issues and delivered.

They fail because of slow performance, poor architecture, and unscalable code.
I'm a Full Stack developer specializing in production-ready SaaS platforms and Electron.js desktop apps — built with React, Next.js, Node.js, MongoDB, and TypeScript. I've shipped 50+ live systems used by real customers daily, including ISP management SaaS, clinic management systems, B2B marketplaces, and cross-platform desktop tools for Windows, macOS, and Linux.
What I build:
— MERN Stack SaaS platforms & admin systems
— Electron.js cross-platform desktop applications
— React / Next.js frontends with SSR & performance optimization
— Node.js / NestJS backend APIs & microservices
— Real-time features (WebSockets, socket. io)
— AI integrations (OpenAI, ChatGPT inside web apps)
— Stripe, Firebase, HubSpot & third-party API integrations
Every new client gets a free 30-minute architecture audit before development starts — so we build the right thing from day one, not refactor it later.
