Technical products that scale.

Twenty years in product and design. I built platforms for 20 million people and a single standard for wine data. The work was always the layer underneath, and what you can design on top of it once it is trustworthy.

Today that is fractional CTO and product work, helping companies modernize and put AI to work, plus two apps of my own.

Product and design are the part I care most about. Usually on a bike once the work ships.
