  • Build
  • Scale
  • Optimize

I'm a full stack developer and software engineer with 2+ years of experience designing and shipping software end to end.

I've built 12+ production-grade products and 10+ frontend projects, working across the stack from interface to infrastructure.

My focus lies in distributed systems and system design, building architectures that stay fast and reliable under real-world scale.

Along the way I've picked up a wide range of modern tools, always favoring the ones that let me move deliberately, not just quickly.
