01 / About
Engineering across boundaries.
I build software where product experience and system behavior have to work as one.
My experience spans enterprise transaction systems, PostgreSQL-backed banking services, real-time interfaces, and an AI sales platform integrated with telephony and CRM systems. I focus on making complex workflows reliable and understandable through sound APIs, useful validation, observable services, automated tests, and careful interface design.
