01 / About

Backend depth.
Product judgment.
Production calm.

I’m a backend engineer who works where distributed systems, real customers, and operational reality meet.

At Amazon, I grew from SDE I to SDE II while building cross-border shipping capabilities across 4+ countries. My work spans service design, pricing systems, AWS infrastructure, compliance tooling, observability, and the operational ownership required after launch.

I’m now targeting high-ownership backend SDE II and selective SDE III roles in India, with Europe as a secondary lane.
