I build secure, scalable backend systems — not just APIs that look good in demos.
About Me
I’m a backend-focused Python developer building secure, scalable systems using FastAPI, PostgreSQL, JWT authentication, and WebSockets. I specialize in solving hard backend problems — concurrency safety, data integrity, and real-time communication — and turning them into clean, production-ready APIs.
I’m currently building PillionPal, a GPS-based ride-sharing backend with live tracking and a mileage-based pricing engine designed for real-world scale.
What I’m Good At
- ✅ Designing secure authentication flows (JWT, OTP, cookies)
- ✅ Real-time WebSockets for live location & event streaming
- ✅ Building clean REST APIs with FastAPI & Pydantic
- ✅ SQL design, atomic transactions & race condition prevention
- ✅ Background automation & task scheduling
- ✅ Writing modular, maintainable backend services
Why Backend?
Backend development is where correctness matters. I enjoy designing systems that are predictable, secure, and resilient under load — from authentication flows to real-time data pipelines. I focus on building APIs that fail safely, scale cleanly, and are easy to reason about in production.
When I'm not writing code, I'm writing stories — world-building through words instead of logic.
