Who I work with
Good fit
- Founders & CTOs in regulated or high-stakes domains
- Teams facing scale, compliance, or architecture bets
- Leaders who need engineering translated for the board
Usually not a fit
- Staff augmentation or body-shop staffing
- Greenfield MVPs without governance or reliability needs
- Hands-on delivery as a full-time engineer on your payroll
