Summary
👤
Senior🎓
Top SchoolDavid Piepgrass is a Chief Software Architect with roughly two decades of hands-on experience building full-stack systems in C++, C#, and TypeScript, and a proven track record of delivering greenfield products from architecture through shipping. He designed and wrote large mapping and planning products (FastNav and Barreleye) as sole or lead developer, blending low-level performance engineering with polished UX across desktop, mobile and web. A prolific open-source author (roughly 300k LoC) he created projects ranging from an SNES emulator to parser generators, language extensions and general-purpose libraries, demonstrating deep expertise in programming languages and tooling. He excels at designing new systems and shared libraries that improve team productivity and product quality, preferring roles where architecture and craftsmanship matter over being “just another coder.” Based in Calgary, he holds a Computer Engineering degree with distinction from the University of Calgary and often oscillates between commercial product work and long-running personal open-source research.
