Systems Architect | Astronomy Enthusiast | Code-Generator-Generator

I spent the last eight years at Microsoft building the "plumbing" for the .NET ecosystem and GitHub Copilot. I like deep-stack mysteries, zero-allocation code, and solving problems that most people don't know exist.

• Now: Somewhere in a different timezone. Quietly busy. Open to the right conversation.
• 2023–2025: Making GitHub Copilot smarter for Razor/C# and building agentic AI prototypes.
• 2017–2022: Maintaining the .NET BCL. If your app has logs or configuration, I likely wrote the code paths you're using.
• Formation: M.S. in Computer Science. Wrote papers on terrain synthesis using curve networks.
• Early Years: Astronomy Olympiads and community building.

"The framework is supposed to feel reliable; I'm not supposed to be visible. That's by design."

• 🌲 BCL Infrastructure: Designed the Logging Source Generator (1.4B+ downloads).
• 🚀 Copilot Accuracy: Pushed C# completion accuracy up by +8% via SimCo eval pipelines.
• 📐 Geometry & Math: My academic roots are in computational geometry and terrain synthesis.
• 🤖 AI Incubation: Built BugBuddy, a RAG-based agentic AI, before "agentic" was a buzzword.

• The Day Job: C#, .NET, Roslyn, LLMs, RAG, LSP, Performance Profiling.
• The "For Fun": Astronomy, Physics, finding bugs in things I use, and reading source code.
• The Vancouver Vibe: Staying local, mentoring, and organizing .NET meetups.
