What I do

Three crafts, one common thread

Different rooms, same instinct: find the technology-based solution and make it work in the real world.

Devmatics, LLC

Build software

As CEO of Devmatics, I lead a senior team building the complicated software other shops won't touch — custom applications, deep integrations, automation, and real AI capability for organizations that can't buy what they need off the shelf.
