AI workflows & developer tools

I build reusable tools around the work that surrounds coding: understanding a codebase, investigating problems, planning changes, and checking the result.

DD Skills

Open-source agent skills

The reusable workflows I use in my development practice, covering app verification, local transcription, coordinated implementation, and campaign production. Each skill packages instructions with the scripts, templates, or references it needs.
