About Jason Fleetwood-Boldt

I've spent 20+ years building large applications: high-quality, tested codebases. I did TDD in Rails from the start, and I've always advocated for pair programming: two developers, one task. Now that coding isn't the bottleneck anymore, and judgment is the name of the game, pair programming feels more relevant than ever.

I'm also a lifelong learner and teacher at heart. I write about the craft (see my "Automated Testing from 10,000 Feet" crash course on testing and TDD) and built Hot Glue, an open-source Rails Turbo toolkit with 100k+ downloads. Mentoring junior engineers through a hard refactor is one of my favorite parts of the job.

On the business side: I've been an IC, a lead engineer, and a VP at Mack Weldon, where the platform my team built scaled the company to $30M. I've also worked as a lead architect bridging strategy and execution at places ranging from early-stage startups to Charles Schwab. These days I'm deep in agentic engineering and LLM orchestration: RAG, vector similarity search, and building AI systems with turn-based state management and autonomous workflows.
