About me
I'm a software engineer with over eight years of experience across backend systems, infrastructure, and developer tooling. I care deeply about clean architecture, operational simplicity, and shipping things that matter.
Outside of work I spend time on personal infrastructure, open source, and the occasional side project that refuses to stay side.
Open to interesting projects and conversations.
