Fractional CTO and technical advisor

I build at the frontier, and bring what works to you.

I spend my time hands-on with early-stage startups, building with the newest tools as they land. Then I bring the parts that are genuinely ready into established businesses that have outgrown their technology.

Thirty minutes, no pitch, no charge.

Selected work

ING · Loan Optics

ING's Innovation Lab wanted new revenue in corporate banking. Reviewing how syndicated loans actually moved between banks and law firms exposed a major gap: no single source of truth for loan data.

That finding became Loan Optics. I built the product and the team from the ground up and led a 12-bank, three-law-firm working group through an end-to-end digital loan simulation. It was later spun out of the bank.

Naturally inclined at shaping digital products and ventures that can meet real users' needs, and very good at communicating with non-tech people.

Selected work

VyBlee

A dispatch and fulfilment idea for commercial kitchens and hotels, with no platform behind it yet.

Took it from concept to a production platform on Laravel, Svelte and AWS with a seven-person team. Transaction volume grew by more than 400%, and the business exited within a year.

He gave the team a clear technical direction, trusted us to own our parts of the product, and was always quick to unblock things. A pragmatic, supportive CTO who really knows how to ship.

Selected work

Ani (formerly BYOB)

A boutique AI workforce product that needed to become something hedge funds, family offices and wealth managers could buy.

Joined as interim CTO, then stayed on. Built a seven-person engineering team across product, data, infrastructure and delivery, and sharpened product-market fit around AI-enabled workflows for finance teams.

Oliver has both the technical and leadership skills you need for a development team, and is not afraid to push boundaries on what is technically possible.

About

Most businesses running on ageing technology don't need a strategy deck. They need someone who can build.

The two halves of my work feed each other. Startups keep me current on what is genuinely ready, not just what demos well. Established businesses taught me governance, security and what enterprise buyers actually demand before they sign. You get both, without the experiments that waste a year, and your team keeps everything I learn.

0115+ years building and leading engineering teams
02Multiple CTO roles, from founder-built prototype to acquired platform
03Led an ING spin-out, Loan Optics, through to international acquisition
04Delivered ISO27001 and Cyber Essentials Plus
05Shipping production AI: retrieval, vector search, agentic architectures
06Angel investor in six early-stage startups
07Still hands-on: Laravel, TypeScript, Python, Go

Portfolio

Where I put my own money.

I am an angel investor in six early-stage companies. This is how I stay current, and it is why I know what is genuinely ready before I bring it into your business.
