I spent a decade teaching .NET how to drive a browser. Now I build the AI agents that drive it for you.
I'm a 7-time Microsoft MVP and a software engineer with 20+ years in the web industry. These days I build AI agents that author, run, and debug end-to-end tests — and the tooling that lets a small team ship with those agents every day.
You may also know me as @hardkoded — that's where my projects live.
- AI agents for testing — agents that explore a real app, write the test, and fix it when it breaks
- Agentic developer tooling — small open-source tools that make working with coding agents less painful, like cronito

I wrote puppeteer-sharp, and the original playwright-sharp that became Microsoft's official playwright-dotnet. I also wrote a book about it all:
