Software Engineer building backend systems at scale

I design and ship backend infrastructure—APIs, event-driven services, and the cloud platforms under them—with a bias toward reliability and systems that hold up under load. Currently at watchTowr.

About

I like hard problems with real constraints—incomplete requirements, production traffic, and systems that have to keep working. I reduce ambiguity fast, design for failure modes before they happen, and ship iteratively. Most of my work sits in backend infrastructure and distributed systems, across cybersecurity, fintech and blockchain.
