About

I’m a software engineer and product-development enthusiast with over six years of experience across backend, infrastructure, and ML-platform development. I like designing scalable, distributed systems and shipping reliable, end-to-end solutions.

My work has spanned consumer products and developer platforms — from payments infrastructure at Paytm, to internal developer tooling at Gojek, to delivery systems at Amazon, to generative-AI infrastructure at SambaNova. I care about robust engineering that translates into real business outcomes.
