I build secure, scalable backend systems — not just APIs that look good in demos.

About Me

I’m a backend-focused Python developer who builds secure and scalable systems using FastAPI, PostgreSQL, JWT authentication, and WebSockets. I enjoy solving hard problems like concurrency safety, data integrity, and real-time communication — and turning them into clean, production-ready APIs.

I’m currently working on PillionPal, a GPS-based ride-sharing backend with real-time tracking and a mileage-based pricing engine, while interning remotely at Zaalima Development, where I ship automation tools used by real users.

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 & preventing race conditions
  • ✅ Background automation & task scheduling
  • ✅ Writing modular, maintainable backend services

Why Backend?

I enjoy building the part of software that users never see but always rely on — the logic, security, and data flow that make everything work. Backend development gives me the space to think about system design, reliability, performance, and how to prevent edge-case failures. I like turning real-world constraints into clean API design and writing code that is predictable, safe, and scalable.

When I'm not writing code, I'm writing stories — world-building through words instead of logic.
