Actions
Strategic Enterprise Architect and technology transformation leader, trusted by senior leadership to translate business strategy into practical technology outcomes. Experienced in leading complex transformation programmes, platform modernisation initiatives, and organisational change that improve operational effectiveness and enable sustainable growth.
I specialise in aligning technology strategy with organisational objectives, helping businesses modernise platforms, improve operational effectiveness, and deliver sustainable growth.
Throughout my career, I have led large-scale transformation and migration programmes, designed business-critical platforms and processes, and influenced investment and technology decisions at senior leadership level. My experience spans software architecture, enterprise architecture, cloud transformation, platform engineering, product delivery, and organisational change.
I am particularly passionate about building clarity from complexity: connecting business strategy, technology direction, engineering culture, and delivery execution to achieve meaningful outcomes.
My approach combines deep technical understanding with pragmatic business thinking, enabling me to act as a bridge between executive leadership, product organisations, and engineering teams.

Deposit-platform architecture patterns
Most fintech engineering writing is about payments or lending. Deposits get less attention, which is odd, because a savings-and-deposit platform has a harder correctness problem than either. You are moving other people's money between regulated institutions, and you have to be right every time, reconcilable after the fact, and defensible to a regulator.
I designed one. Here are five patterns that held up. None are novel on their own. The value was in choosing them together, early, and refusing to compromise on the correctness ones under delivery pressure.
Skills as a cross-functional operating model
Most writing about AI "skills" is engineering writing. Reusable prompts, agent tools, coding patterns. Useful, but it stops at the engineering boundary. The more interesting thing happened when ours crossed it.
We built a shared catalogue of reusable skills. Each one encodes a decision made once, so it never has to be made again. Engineers built them, agents used them, demand grew for more. That much was expected. Then risk, compliance, and content teams started contributing.
AI Adoption - Measure the middle, not the frontier
When a company rolls out AI tooling, the metric everyone reaches for is how much more the best people can now do. It is the wrong metric. Your vanguard was always going to run. They would have found the tools without you. Measuring them tells you how fast your fastest can go, which is a number that flatters you and predicts nothing.
The metric that matters is whether your cautious middle is moving.
