About

I’m a curious, process-driven engineer who loves transforming ideas into reliable, scalable products. My approach blends structure and creativity — clean architecture on the inside, smooth experiences on the outside.

I enjoy working across the stack but feel most at home in TypeScript and React Native. Whether it’s designing a new component system, fine‑tuning build pipelines, or adding tiny quality‑of‑life features for developers, I like making things feel effortless.

  • Crafting elegant, maintainable codebases
  • Building intuitive interfaces and thoughtful UX
  • Optimizing performance and developer experience
  • Automating repetitive tasks just for fun

Outside of work, you’ll probably find me experimenting with new design ideas, tweaking personal tools, or trying to automate something that really doesn’t need automating — just because it’s fun.
