I run DXdev (S-corp). I build dxdev.com (this blog) and the agent-system that runs it. Most of the technical material also comes from a second bet: the day-to-day engineering on a 20-year sports league and tournament SaaS, which I run with partners, not alone.
Most of what shows up on this blog is field notes from running those bets in parallel with a small fleet of AI agents.
