01 — About

I'm a Senior DevOps & Systems Engineer with over a decade of experience across startup and enterprise environments. I specialize in building infrastructure that scales, automates the tedious, and keeps production running without drama.

From Kubernetes cluster ownership to ML-driven incident response, I bring a reliability-first mindset to every layer of the stack — infrastructure-as-code, CI/CD pipelines, embedded systems, and everything in between.
