About

A little about me

I'm an AI and systems engineer based in India, currently on the founding team at Datatailr, where we build high-performance computing tools for hedge funds and high-frequency traders. My expertise lies in bridging AI with robust infrastructure, working extensively with vector databases, RAG, and MCP. My work lives in the parts of software you only notice when they break: cloud infrastructure, private networking, orchestration, and the systems that quietly hold everything up.

Before that I wrote Rust for a payments engine at Juspay, automated supply-chain workflows at IBM, and spent a GitHub Externship building WebAssembly tooling. Somewhere along the way I fell hard for competitive programming and never really stopped.

This site is the version of me that a résumé can't hold: the writing, the photographs, and the long habit of picking up whatever problem looks most interesting. Have a look around.
