Fractional data andtransformation lead.

I'm Barbara. I help businesses and founders make decisions about data, systems and AI, and lead the work that follows.

You can bring me in for one to four days a month, or have me join your team for a three to six month engagement. I take responsibility for the work, from deciding what needs to happen through to delivery.

I've spent ten years working across finance, government, property and infrastructure including Barratt Redrow, Fidelity Investments, Aviva Investors, UBS, the Department for Transport, UKHSA and Mott MacDonald

I · What I Do

I lead data migrations, system replacements and reporting rebuilds. I also help teams work out where AI is worth pursuing, and how their people and processes need to support the technology.

I've spent ten years leading this work. I've built teams, replaced platforms and helped get programmes moving again when leadership and delivery had lost touch with each other.

I run Stratford Ellis, my consultancy, with a small team behind me. I'm based in London and work wherever I'm needed.

II · Who I Work With

Who I work with.

For businesses, I lead data and transformation work, help resolve stalled programmes and provide independent reviews. For founders, I bring senior experience in data and AI at a stage when a full-time hire may be too much.

III · For Business

Working with your business.

You might be choosing a new system, trying to get a migration finished, or wondering why your reports disagree. There are six ways we can work together.

The Engagements

Each one shows what it covers and how long it takes.
