Ibuilt a company and sold it. I wrote the portal a lender's investors log in to, sitting beside the CEO and the CTO. I lead fifteen analysts on a research desk. The thread through all of it is the same — I want the moment code stops being a repository and starts being somebody's Tuesday morning.

Computer Science and Mathematics at the University of St Andrews, by way of Alicante. Selected for Morgan Stanley's technology programme, currently building inside a fintech lender, and still shipping products of my own. Below is the record, in full, most recent first.

The ledger

Every engagement, open one to read it

An investor portal built from scratch beside the CEO and CTO, so investors can see exactly what their money is doing. Live inside the business, admin access only.

Three at length

The pieces worth more than a line

Case one

Showing investors their own money

A lender knows precisely what every pound is doing. The people who supplied the pounds usually do not — they wait for a quarterly PDF and take it on faith.

I built the portal that closes that gap, from an empty repository, working directly with the CEO and CTO. It is behind an admin wall, so there is no link to click here; what it taught me was unsecured lending, investor reporting and how a fintech product actually reaches the people it is for.

Case two

Founded, grown, sold

WorkRoad started because school ate evenings that should have belonged to us. It became a productivity app built on the idea that smart work beats long work, and beta testers finished tasks around 40% faster than with what they had been using.

Two years after launch it was acquired. The build was the easy half — the education was in the diligence, the paperwork and handing something over cleanly.

Case three

One academy, one engineer

A language school in Playa de San Juan needed everything at once: a site, a way for teachers and students to organise themselves, and payments that simply worked.

I designed and still run the whole stack — MERN, Stripe, Vercel — as the only technical person on it. Working that closely with an owner taught me more about a product life cycle than any brief could.
