What I'm looking for

I seek meaningful remote work at mission-driven companies prioritizing healthy culture, technical excellence, long-term impact, and sustainable pace.

I am a backend engineering leader with over 20 years building high-impact platforms across justice, logistics, and e-commerce, focused on performance, maintainability, and user value.

I combine deep technical expertise in distributed systems, cloud-native architectures, and observability with a people-first leadership style — mentoring teams, driving technical initiatives, and improving developer experience.

My track record includes redesigning data pipelines, reducing operational toil through automation, architecting low-latency search platforms, and leading cross-functional modernization efforts to deliver measurable business and engineering outcomes.
