About

I'm a Machine Learning Engineer working on applied AI and ML systems.

I'm interested in agentic systems and making LLMs useful beyond chatbots. Recently built Protostar, a browser copilot that brings Cursor-style intelligence to web browsing.

When I'm not working, I mostly play Soulsborne games like Elden Ring and other RPGs. I also tinker with side projects and occasionally write about things I'm learning.
