About

I build backend systems where reliability and performance are non-negotiable — the kind of infrastructure teams depend on without thinking about it.

Backend & infra
Currently
Staff @ Stripe

Most of my work sits at the intersection of distributed systems and developer experience — making complex pipelines feel simple to operate. I care about observability, graceful degradation, and code that survives the next engineer.

Before Stripe I spent years on edge runtime and metrics ingestion at Vercel and Datadog. Outside work I contribute to open source, ride long climbs on weekends, and maintain an unreasonable opinion about keyboard switches.
