An operator who builds — turning back-office problems into systems that run themselves.
About · The Operator

From auditing the numbers to building the systems.

Finance by training, builder by instinct. I turn manual processes into systems — building fast with AI, then learning how they work by doing.

The Background

Finance & operations, with a build habit.

My background is finance — audit at PwC and KPMG, fund services, and private-equity fund finance, across Jersey, London, Singapore and beyond. ACCA qualified, with an MSc in Data Science. Years in the detail of how finance operations actually work taught me where time leaks out of a business: the thirteen-step process that should be one.

More recently I've started building the fixes myself, with AI, instead of just specifying them — learning fast by doing.

The Method

Research first. Build it right. Automate the repeat.

Every build starts with research, then a clear scope, then the smallest system that removes the manual step. I would rather do something once and well than thirteen times by hand.

Tables over prose. Plain-language risk flags. Output that can be forwarded with zero cleanup.

The Approach to AI

Practitioner, not theorist.

I am not a career developer. I translate business needs into structured processes, build fast with AI, then learn how it works by using and fixing it.

No hype, no thought-leadership. Real examples, specific tools, what actually shipped.

I keep a running glossary of the terms I meet as I build — jargon explained in plain language, not hidden.

Working with the Personal OS

What an engagement looks like
Capture

Find the leak.

We map where your time and information actually go — the repeated manual steps, the lost context, the reports rebuilt from scratch each month.

Process

Build the smallest system.

One automation that removes one manual step, wired into the tools you already use. Documented so it can be handed over, not hoarded.

Digest

Make it run itself.

Schedules, alerts that only fire when something breaks, and a brief that reads the system back to you. Silence means healthy.

I'm open to conversations about building systems in finance & operations — and about the work above.
