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.

Let’s build something consequential.

I’m interested in senior software engineering roles where I can own product-facing systems across the stack, strengthen engineering foundations, and help teams ship reliable software.
