Hi, I'm Matthew Fontana.

I build the platforms that make AI coding tools actually work for engineering teams. I write here about what I'm learning along the way.

Currently Staff Engineer at Airbnb. Previously Spotify, UPS.

  • Write here on agentic developer platforms, MCP, evals, and the agentic SDLC.
  • Speak on podcasts, at conferences, and inside engineering orgs.
  • Ship open source on GitHub (aitk, claude-code-toolkit, claude-tmux-manager, and other Claude Code tooling).
  • Run TabletopAdventureCreator.com, a generative-AI SaaS in production since 2022.
  • Help a handful of engineering teams a year build the platform layer underneath their AI tools.
