With nearly 35 years in IT, having spun up my first web server in 1993, my engineering roots run deep. I have architected and built everything from desktop and web applications to complex full-stack solutions.

How fractional CTO engagements with Erwin work
Erwin works on a fractional basis — typically one to three days a week for an agreed engagement length — so you get senior technical leadership without the cost or commitment of a full-time hire. Engagements commonly include technical due diligence, board reporting, engineering team leadership, technology strategy, architecture reviews, hiring support, and stepping in as interim CTO during a transition.
