AI tooling and developer experience PM | formerly in .NET team at Microsoft.
Avid gardener. Lover of music. Always learning the guitar.
Adventures in the Perplexity Comet browser - organizing my GitHub project! This is a fun one - First I asked it to create issues out of a bullet list and interview me for details. Now, I had it create a project and work on stack ranking those ideas. Wonderful time saver

Been having fun diving deeper in to AI app development with the Python ecosystem lately. So many great libraries - I'd love to see more of this type of open source ecosystem forming for .NET/C#. Beyond the excellent Microsoft-built libraries, anyone have a favorite .NET + AI library?

Looking around at the latest state of AI evaluation libraries for C#/.NET developers. I spotted that there's an EvaluationClient API for the OpenAI .NET SDK now! Tried to play with it, but seems like the API surface isn't there just yet. What a tease!

Nearly ready with a new blog - I'm loving the simplicity of GitHub Pages for this. Last time I had a blog I used the Ghost blogging engine, which was cool but overly complicated for my needs in hindsight. I went looking for my old blog content and it's all formatted HTML stored in SQL Lite.
