Senior software engineer building resilient backend systems.
I'm Sourav — seven years shipping REST APIs, optimizing databases, and automating backends across monoliths and microservices. I design clean, scalable systems that move metrics, not just tickets.
01 — About
A backend engineer who treats systems like products.
I'm a backend engineer with 7 years building scalable, high-throughput systems. My day-to-day lives in REST APIs, database performance, and backend automation across both monolithic and microservices architectures.
I lean toward clean, maintainable code and measurable outcomes — shaving turnaround times, cutting manual ops, and shipping infrastructure that scales quietly. I work the full stack of the back end: design, query plans, queues, deploys, observability.
