A few words

I'm a software engineer with 14 years shipping across the stack — full-stack web, mobile, backend, platforms, payments and telematics. I like the unglamorous parts: billing rails, lifecycle orchestration, observability, the systems that have to be correct at 3am.

Today I'm on Microsoft's Consumer Commerce team in Redmond, building the subscription infrastructure behind Microsoft 365, Copilot and Xbox Game Pass. After hours I self-host most of my own infra and build open, privacy-first side projects.
