I build backend systems, event-driven architectures and practical automation. Mostly Java & Spring — with a strong interest in infrastructure, hardware and systems that actually run.

About

engineering over decoration

I am a self-taught Java programmer working primarily on backend systems and distributed application architecture.

My work sits at the intersection of application development and infrastructure: APIs, messaging, persistence, containers, observability and automation.

Outside of day-to-day software engineering, I enjoy turning hardware and home infrastructure into reliable, programmable systems.
