I build AI-powered applications, registration and event platforms, and workflow automation that hold up in the real world — not slick demos that fall apart the moment real users show up. My background is in enterprise technology leadership, including serving as Chief Technology Officer for a state government agency, so I bring a strategic, business-first lens to every engagement. I don't just write code; I think about how it fits your bigger picture and what it has to do once it's live. I'm especially known for building registration, check-in, and conference platforms that run real events end to end — online registration, secure payments, attendee management, badge generation, on-site check-in, and companion mobile/PWA apps. These aren't prototypes. They're systems that have processed live attendees, payments, and event-day logistics without falling over.

I'm at my best taking a messy idea or rough concept and turning it into something structured, functional, and polished. Whether you need a complete platform or a single smart component that makes your product better, I can get you there. I work quickly, communicate clearly, and I don't disappear mid-project. If you're looking for someone who understands both the technology and the business — someone who's led teams, managed vendors, and shipped systems people actually depend on — let's talk.
