Founder & CEO · Quadratic Digital
Cloud architecture, product strategy, and the engineering behind both. I run Quadratic Digital, where hard problems become working systems.
I'm an architect, a product manager, and an executive leader — and I've never stopped building. I set the technical vision, own the product, lead the teams, and stay close enough to the code to know it's right. I run Quadratic Digital, the enterprise umbrella behind several ventures: a federal IT and GovCon practice, a payments and recurring-billing platform in Quadratic Financial, and a game studio in Quadratic Studios. Government contracting is one vertical — not the whole company.
My work lives at the unglamorous, high-stakes layer: Medicare claims systems measured in decades of mainframe history, payment rails that can't drop a transaction, access control that has to fail safe. Fifteen-plus years in — a dozen on the mainframe, a decade architecting in the cloud, a decade leading the teams that ship. The overlap is the point: modernization means standing in both systems at once, so I was building in the cloud while the mainframe was still the system of record. I still like problems where "mostly works" isn't an answer.
I'd rather hand you a running proof of concept than a roadmap. The vision, the architecture, and the product strategy behind my ventures are mine — and I see them through to something real, whether it's a Medicare claims engine, a video game, or the Raspberry Pi running my house.
Recent proof: a payments platform in production, clearing real transactions for real businesses. Tarmac Tycoon, taken from concept to the App Store. And in build — a real-time claims-adjudication engine for Quadratic Direct, and infiniti2, a cloud-based access control system running multi-tenant across Raspberry Pi and OSDP v2 readers with a hardware root of trust.
The technical foundation under every venture — the same architecture and product discipline whether it's a federal claims system or a video game.
Secure, scalable, automated systems on AWS — built for environments where compliance and uptime aren't optional.
Turning an idea into a roadmap and a roadmap into a shipped product — owning the strategy from concept to launch.
Moving decades-old mission systems off the mainframe without losing the institutional logic baked into them.
Practical model deployment and tooling that earns its place in a workflow instead of demoing well and dying.
15+ years in product development, specialized in Medicare policy and claims processing. 10+ years hands-on with the mainframe systems most people only modernize from a distance.
