A Bit About Me

I'm a software engineer who enjoys building full-stack applications from the ground up. I gravitate toward projects that solve real, tangible problems — whether it's helping people understand their equity compensation, track investment performance, or simply organize their favorite recipes.

My toolkit centers on the TypeScript/React ecosystem — Next.js for web, React Native for mobile, backed by cloud infrastructure on Azure and Supabase. I care deeply about performance, clean code, and crafting interfaces that feel great to use.
