Engagements
Architecture & system design
Translate a business problem into a system: the right components, the right boundaries, the right tradeoffs — delivered as something a team can build from.
Build & integrate
Take a system from architecture to running production — web, embedded, and the integration layer that makes them one system instead of five disconnected tools.
Modernize & scale
Pick up a system that is creaking — slow, brittle, expensive — and rework it so it grows with the business instead of against it.
