About

I'm a frontend engineer who cares about the full picture: clean architecture, fast performance, and interfaces that feel right to use. I specialize in the React ecosystem and have shipped production applications across fintech, ecommerce, and analytics domains.

I think a lot about how design and engineering overlap. Good UI is not just pixels matching a mockup; it is fast load times, accessible markup, and thoughtful interaction patterns. I bring that product sensibility to every feature I ship.
