How can I help?
I’ve been around computers my whole life and inside technology companies for 8+ years — as a CTO through exit, a consultant, and an operator where tech meets finance. Bring me the problem. I’ll find the right fix, and usually build it too.
Our website is slow and nobody here can update it.
Yes. Rebuild it on something your team can edit.
We re-type every order into three different systems.
Yes. Connect them and retire the busywork.
We need a CTO, but we can’t hire one yet.
Yes. Fractional, until the right hire lands.

01 — How I help
If it runs on a computer, there’s a good chance I can help.
An afternoon or a year, a laptop or a platform. Here’s a sample of what people bring me — in their words, then mine.
02
Custom software
“We need an app — or a portal, or a tool — that doesn’t exist yet.”
→ Web and mobile apps, customer portals and internal tools, built around how you really work.
03
Automation & integrations
“We copy the same data between five systems by hand.”
→ Connect the tools you already pay for, automate the busywork, and stop the copy-paste errors.
04
Data & reporting
“I can’t get a straight number out of our own data.”
→ Clean pipelines, dashboards people trust, and financial and operational reporting that adds up.
05
AI, applied sensibly
“Everyone says we should ‘use AI.’ Where, exactly?”
→ Find the use cases that pay off, prototype them on your real work, and skip the hype.
06
Cloud, infrastructure & security
“Our setup is held together with tape, and the bill keeps growing.”
→ Sound cloud architecture, cost clean-ups, backups that restore, and sensible access and security.
07
Office IT & everyday tools
“Email, laptops, logins, licences — it’s all a bit of a mess.”
→ Workspace set-up, picking the right software, smooth onboarding and offboarding, sane permissions.
08
Technical leadership
“We need a CTO, but it’s too early to hire one.”
→ Fractional CTO: roadmap, architecture, MVP launch, hiring and investor-ready tech diligence.
09
Rescues & second opinions
“Our developer vanished and the project is stuck.”
→ Code and vendor reviews, a plain-English diagnosis, then stabilise it and get it moving again.
Don’t see it on the list? Ask anyway.
Odds are I’ve done it, or something close. And if I’m not the right person, I’ll tell you — and point you to who is.

03 — About me
A lifetime around computers. 8+ years doing it for a living.
I’ve been taking computers apart, building things on them and fixing them for friends for as long as I can remember. I’ve worked in technology professionally since 2018, in and out of technology companies — including as CTO of a climate tech company through to its exit, as a consultant, and in roles where technology meets finance. That range is the point: I’ve seen problems from the server room, the boardroom and the spreadsheet.
BuilderHands-on across the stack — from a laptop set-up to a production platform.
OperatorBuilt and led engineering at a startup, from early product to exit.
Finance-fluentSpeaks budgets, unit economics and investor diligence.
04 — Why one person
One call instead of five vendors.
The whole problem, one person
No hand-offs between a designer, a developer and “the IT guy.” I see how the pieces connect.
Plain language
You’ll always know what I’m doing, why, and what it costs.
Honest scoping
If an off-the-shelf tool or a smaller fix will do, I’ll say so before you spend.
Business first
Every recommendation ties back to cost, revenue or risk — not tech for its own sake.
Your turn
So — how can I help?
Tell me what’s going on in a sentence or two. I’ll reply personally within 2 business days with a straight answer — even if that answer is someone else.
