About this gig

Need a solid backend for your app or startup idea? I build clean, working REST APIs using Flask or FastAPI with database setup (SQLite, PostgreSQL, or MongoDB), user authentication (JWT or session-based), and proper API documentation.


I've built backends for AI health platforms, journaling apps, and multi-agent SaaS systems, so I know how to structure code that's easy to extend later, not just a quick hack.


What you get:

- Working API with documented endpoints

- Database schema designed for your use case

- User login/signup with secure authentication

- Clean, commented code with setup instructions


Message me with what your app needs to do before ordering I'll confirm the scope so there are no surprises on either side.

Full-stack developer and AI/ML builder from India, currently studying CSE (AI/ML). I've shipped 14+ production-grade projects - from AI health platforms using XGBoost to blockchain-verified deepfake detection systems. I specialize in fast, clean builds: Python/Flask/FastAPI backends, React frontends, and ML model integration. Top 10 finisher at a 100+ team hackathon. I reply fast, communicate clearly, and care about delivering something that actually works - not just looks good in a demo.
