About

What I do

I'm a software engineer with 2+ years of experience, currently at TATA 1MG. I work mostly on backend systems in Python and FastAPI — APIs, payments, caching, and data pipelines.

Performance

I profile slow endpoints and fix them — caching, query tuning, and async work. One API went from 48s to 2s.

Distributed systems

I work with Kafka pipelines, background workers, and search-backed analytics, and I think about what happens when a service fails.

Production code

I care about clean APIs, readable code, and observability — not just getting something working once.

Projects

Something I built on the side

Smart Parking App

A parking reservation and payment app. I built the REST APIs, designed the relational schema, added OAuth 2.0 login, and integrated Razorpay for payments.

Handles the full booking-to-payment flow end to end.
