About

Complex problems, clear systems.

I care about scalable architecture, maintainable code, and the resilience of distributed systems. I’m at my best when collaborating across teams, sharing knowledge, and turning hard technical constraints into pragmatic solutions.

My next step is growing toward technical leadership while continuing to stay close to architecture and engineering craft.
