Matt Maas

Software engineer · 8+ years of enterprise C#/.NET, now also shipping Android systems work, TypeScript tooling, and AI-agent infrastructure · Omaha, NE · Available for FTE and contract roles

What I Do

  • C#/.NET engineering and modernization — REST APIs, Entity Framework, SQL Server, Azure DevOps CI/CD; legacy WPF audits, repair sprints, and .NET upgrades
  • AI-agent infrastructure — MCP servers, multi-agent orchestration, voice agents, and evaluation harnesses with explicit safety routing
  • Hardware-adjacent Android — Magisk modules, Quick Settings tiles, Bluetooth input devices, AR-glasses display control; 3 Android APKs published via GitHub Releases

The .NET work is what I've been paid for; the public repos below are what I build when nobody's paying.
