I sit on the board

You need confidence that the numbers in the room can be trusted, and that AI adoption is governed well enough to withstand scrutiny.

Take the readiness diagnostic

I own the numbers

As a CFO or finance leader you need reporting you can defend, efficiency you can evidence, and a clear read on where data quality is costing decisions.

Decision-grade data

I'm a PE operating partner

You need a fast, honest read on a portfolio company's data and AI maturity - and a value path that survives diligence.

Readiness diagnostic

I answer to a regulator

You need AI adoption and data controls that survive examination - classification, accountability, and evidence, not governance theatre.

Regulated AI governance

Each seat has a fuller path. See all four routes

The data function only matters when it changes the quality of decisions.

Fragmented data is not a technology problem. It is a board-level decision problem, a regulatory control problem, and a commercial performance problem.

His work sits where commercial performance, regulatory control, and executive decision quality meet: building data functions, modernising platforms, improving data quality, and creating governance that gives senior leaders confidence in the numbers.

He combines board-level credibility with hands-on technical fluency in Python, SQL, cloud data platforms, applied AI, RAG patterns, knowledge graphs, and agentic systems. That mix matters because the hardest executive data decisions are rarely solved by a platform selection alone.

The consistent thread is pragmatic transformation: turning fragmented data estates into decision infrastructure that can be governed, audited, scaled, and used by commercial teams.

Proof that connects engineering, governance, and executive outcomes.

Short case studies and the senior roles behind them: operating context, intervention, and measurable result - not a list of logos.
