I build architecture and software development teams that run without me.

Who this is for
For CTOs, heads of digital and delivery leads with a programme that has to land; for platform vendors who need an architect their partners trust; and for architects, engineers and leaders who want to learn from someone who has done the work.
I take on the programmes where getting it wrong is expensive, put the right people around them, and teach until the team runs without me. Careful with risk, generous with what I know, and accountable for what I promise.
Three ways to engage
Presales and solution engineering
Architecture for the pursuit: solution shaping, estimation, orals and proof-of-concept.
Pursuit support, scoped to the bid
Post-sales architecture and engineering
Rescue, performance and security hardening, migration, and handover to the client's own team.
Fixed-scope architecture assessment, or a defined recovery phase
Team enablement. Hands-on 48-contact-hour intensives and standing architecture guilds for architects, software engineers, developers, IT professionals, IT managers and IT executives. Participants build and deploy a capstone, not just attend.
All six ways to work with me, including mentorship and coaching, and the terms
How I work
Deliberate
I draw the risks out early, weigh them in the open and design for them. You get an architecture that anticipates what goes wrong, not one that discovers it in production.
Accountable
What I say I will deliver, I deliver: on the date, on the budget, with the evidence trail an enterprise will accept. My word is the contract behind the contract.
A builder of teams
I recruit, arrange and steady the bench, set the standard, then hand it over. Three delivery centres, a 1,500-strong practice and every programme since were built that way.
A teacher first
Twenty-five years of paid teaching, from secondary-school mathematics to enterprise architects. I explain until it is understood, write it down, and leave the knowledge with you.
Still learning, still coding
Thirty-eight AI courses in one year, an Agentic AI Nanodegree and a public architecture series. I do not architect systems I could not implement myself.
Competitive on your behalf
I like to win the pursuit and then win the delivery. High stakes bring out my best work, and I want the ball when the game is on the line.
