About the principal advisor

A CTO Who
Still Builds

I'm William Fawthrop. For more than 27 years, I've helped teams untangle hard technical problems, make better decisions, and deliver systems that support the business instead of slowing it down.

The Common Thread Is
Business Impact

A cloud bill, a legacy codebase, a slow engineering team, and a leaky sales process look like different problems. Usually they are connected by the same missing piece: nobody has the context and authority to see the whole system and make the tradeoffs.

That is the role I play. I connect the technical decision to the operating cost, the customer experience, the team's ability to deliver, and the company's growth target. Then I help put the decision into production.

How I work

Audit first. Build second. Stay accountable.

Engagements can begin with a focused audit, move into modernization or automation, and continue as ongoing fractional CTO support. You can hire me for the diagnostic, the implementation, or both.
