What I do

A software engineer whose focus is AI consulting — advising on implementation, then building it.

I've shipped production software for over a decade — React, Node.js, Rust, cloud. I put that depth into consulting on AI implementation: finding where AI creates real value for a business, designing the approach, and then developing it end-to-end. Strategy and engineering from one person — so what we plan actually ships.
