Founder of DatPilot
DatPilot is the company I founded to turn the tools behind my own websites into products other people can use.
Every DatPilot product started as an internal tool. I run it daily on my own portfolio until it is reliable, then package it for customers. Claude Code is my engineering partner across the whole codebase.
