I build resilient, high-throughput backend systems and the cloud infrastructure that keeps them running at scale.

Engineer, problem-solver, systems thinker.

With over eight years of experience shipping production software, I specialize in distributed systems design, API architecture, and cloud-native infrastructure. I've led teams through critical migrations, cut infrastructure costs by double-digit percentages, and built platforms that serve millions of requests daily.

My approach is pragmatic: ship fast, measure relentlessly, and keep the blast radius small. I care deeply about developer experience, observability, and writing code that the next engineer can actually read.
