About

Systems over demos.

I got into engineering through competitive programming. Years of Codeforces rounds taught me to reason about correctness and complexity before writing a line of code. That habit stuck: I am drawn to systems where getting it wrong is expensive: durable execution, data capture, and production backends. Day-to-day I also ship product surfaces people depend on. Outside of work I still do CP rounds and tinker with systems projects in Go and C++.

Open to software engineering and founding-team opportunities, especially where backend depth, product ownership and reliable systems matter.
