Product-minded engineer
Building reliable, elegant software with purpose.

Strategy, architecture, delivery.
About
Pragmatic, outcome-focused, and calm under pressure.
I bridge product thinking with engineering execution. I thrive in ambiguous environments, clarify priorities, and ship incrementally with high quality. My toolkit spans system design, API platforms, and polished user experiences—always measured against business impact.
Recent focus areas: platform reliability, onboarding flows with measurable conversion lift, developer tooling, and observability. I care about sustainable velocity: clear interfaces, thoughtful defaults, and excellent documentation.
