> Weekly AI model tracking, agentic development experiments, and practical dev tools from a 20-year software engineer in Kansas City.

I've been writing code since around 2000 and writing about it almost as long. The blog covers AI model comparisons tracked weekly, agentic development using AI agents to build real software, vibe coding experiments, Obsidian plugin development, and self-hosted AI agents. I also write books and freelance technical content.
