Technology leader who builds teams and systems that scale. CTO, architect, and lifelong learner.

About

Still building things.

I've spent my career architecting cloud platforms, leading engineering teams through acquisitions, and shipping software that serves millions of students and educators.

My work spans Higher Education, K-12, and Non-Profit sectors — always at the intersection of complex systems and real human impact.

These days I'm deep into AI agent orchestration, and I'm looking to bring that experience to a board role where strategy meets technology.

Some things never change — always building something.
