01 / About

Good software starts
with good judgment.

I’m a software engineer in Phoenix, Arizona, with 14+ years of experience turning complex problems into dependable systems.

My work spans NASA ground infrastructure, streaming experiences at Angel Studios, financial services, and custom platforms for businesses. I’m at home connecting the details of implementation to the bigger architectural picture.

Through Phi Technology Solutions, I help businesses build thoughtful digital experiences. I also explore how AI and developer tooling can make engineering more effective.
