CS student, class of 2029.
I like building things that are fast, small, or slightly cursed.

Experience

Research Engineer Intern · Undisclosed startup July 2026 - Present Burning GPU credits is all I am allowed to say.
Research Intern · Language Technology Research Centre, IIIT H Apr 2026 – present DPPNets, graph schedulers & NPU perf, using Qualcomm NPU SDK

Previously, I've also helped to build an analog circuit optimizer used by Micron and a risk moderation engine for BuyMeACoffee (YC W19). I also run Grafite which provides funds to build physical engineering projects of my peers.

Shorter pieces live under essays.

When I was just starting out in 2025, some of my projects hit the HN frontpage, some were loved on r/unixporn and r/developersIndia, and some got a lot of traction on Twitter. Since then, I have pivoted towards research engineering, and most of my work remain under strict NDAs.
