About me

I'm a senior software engineer with 12+ years building and modernizing systems that people rely on but rarely think about. My work spans public-sector, healthcare, and commercial software — a county retirement system, a US healthcare EHR, national identity and passport systems, and high-traffic e-commerce.


I work across the stack — Java, C#/.NET, React, and Node — with a focus on distributed architecture (microservices, Apache Kafka, PostgreSQL) and the interfaces that surface it. I like the unglamorous parts that make software trustworthy: data migration, reconciliation, authentication, and reliability. I've led teams of 4 to 10, and I still write production code.


Right now I'm deepening my work in AI — completing an AI Engineering credential and studying generative AI — because I think the engineers who stay valuable are the ones who learn to build with these tools. I also teach data structures and algorithms as an adjunct instructor.
