About

I've built my career at the intersection of software engineering and business problems.

I started as a hands-on developer, building enterprise and mobile software, evolved into senior engineering roles, and eventually moved into technical leadership — designing architectures, leading engineering initiatives and translating business priorities into technical execution.

Along the way, I've worked across aviation, fintech and education, contributed to high-volume systems, co-created software products and led initiatives around cloud, CI/CD, software quality and distributed architectures.

Today, I'm particularly interested in the intersection of Software Architecture, AI Engineering, Product and Technical Leadership.

I enjoy problems where engineering decisions have a measurable impact on both the product and the business.

Let's build something that matters.
