About this gig

Need a backend that will not fall over once real traffic hits it?


I build REST APIs and database architecture with Node.js and PostgreSQL secure, properly structured, and ready to scale as your product grows.


What you get:

  • REST API built with Node.js and Express
  • PostgreSQL schema design, normalized and indexed properly
  • Authentication and role-based authorization
  • Third-party integrations (payments, email, storage, etc.)
  • Input validation and error handling done right
  • API documentation
  • Deployment and environment setup


How I work:

  1. We lock the scope endpoints, data model, integrations
  2. I design the database schema and API structure
  3. I build the backend, with regular progress check-ins
  4. We test every endpoint against the agreed scope
  5. I deploy and hand over source code and documentation


You get clear communication throughout, not silence until delivery day, plus bug support tied to the agreed scope after launch.


Every backend is different before ordering, message me your feature list, expected data model, integrations, and existing code if any, and I will tell you honestly what fits.


Third-party fees and out-of-scope features are not included.

Hey, I'm Sagar — a full stack developer who specializes in getting AI features into production, not just into a demo. I build the web app, mobile app, or backend around the AI layer (OpenAI, Claude), not the other way around, which is usually where things break for teams that bolt AI on late. 90+ projects, 5.0 rating, real companies. Stack: React, React Native, Node.js, TypeScript, Firebase, MongoDB, PostgreSQL. Send me your idea and I'll tell you honestly what it'll take to build it right.
