PracticeThree ways I work

Advise, build, invest.

The goal is the same every time: systems that work and keep working.

AI strategy and transformation

A senior partner for your AI plans, without the hype.

Working out where AI fits in your business, what to do first, and how to roll it out safely. I also work as a fractional CTO, and help teams show how AI is actually being used and controlled.

Build to production

Systems your team can trust.

Secure cloud architecture and backends come first. AI agents and private search over your own data come next, when the job needs them. Every build is treated as a security problem, not a demo.

Invest as an operator

A few careful bets on software and infrastructure.

I back early-stage companies where the build still matters, and I stay involved instead of watching from the sidelines.
