01About

Building the future,
one commit at a time.

Software Engineer with 3+ years shipping production-grade systems at scale. I work at the intersection of clean architecture and impactful user experience — from AI chatbots to payment dashboards processing millions of transactions.

I care about the parts users never see — type safety, build pipelines, observability — because they're what make the parts users do see feel effortless.
