Twenty years inside UN-scale institutions, restoring trust in the data behind decisions worth billions. Now with a council of AI models I direct.

Hard decisions, turned into models you can interrogate.

Three cases below, every one of them live. Change the criteria and reach your own verdict. Then decide whether we should talk.

Three ways to work with me: a conversation, a decision stress-test, or the CV.

01

Three decisions, rebuilt as models you can play with.

Each one is a decision somebody had to make. The problem, what I did, and what changed. Open any of them: move the criteria, open the evidence behind a number, and see whether the recommendation still holds.

The problem

A network of 150 offices orders USD 3.25B a year through 160,550 purchase orders. Standard BI shows the transactions. Nobody can say where to look first, or which number can be trusted.

What I did

The spend-mapping and office-clustering method I ran by hand inside a global institution from 2012, rebuilt with AI as an agency-neutral engine: a five-mark scorecard (fit, efficiency, price, resilience, local economy) against 150 peers, with every finding opening its chart, its table and its method, in that order. Everything is a signal to review, never a verdict; the controller decides.

Health Systems Are Decision Systems

The problem

Where a child is born sets a thirty-year gap in life expectancy before a single choice is made. Global health has no shortage of actors or money; they flow in different directions, and only about a third of the signal in raw data reaches a decision intact.

What I did

Public-health, financing and outcome data reconciled into one model, then challenged by four AI models for gaps and overclaiming before any chart was drawn. Built as six scroll-driven chapters where the reader holds a real-sized budget and moves the money, and the ecosystem of funders, ministries and communities responds live.

The Fragility Lab

The problem

A 4.8× recommendation looks robust on paper. Then reality intervenes, and the biggest number is usually the one whose model is most wrong in your favour.

What I did

Each of four parameters is estimated from imperfect evidence. The tool runs a hundred scenarios and maps the whole parameter landscape, so the gap between the optimistic number and the realistic spread is visible. Knowing where a model breaks in the field is twenty years of institutional work, not a statistic.

02

One promise, verified twice.

Most analysis asks you to trust two things you can't see: that the data is sound, and that the reasoning is sound. I make both inspectable, before a decision is made on either.

Most decisions don't fail at the strategy. They fail at data nobody could trust, and reasoning nobody could check.

At a major UN agency, reconciling 500,000 procurement lines by hand took two months. The same first reconstruction pass now takes a day, complex domains then iterate from there. That speed isn't the product; it's what makes the rest possible: once the foundation is sound, I rebuild it into something a board, or a regulator, can defend.

Council of Models

Several AI models as a challenge panel, not one source of truth. They disagree, stress-test each other, and surface the blind spots. Human judgement is the synthesis layer.

Data trust

Turbo Reset

Chaotic, unreliable data rebuilt into a clean, structured, auditable foundation in a day, with every value traceable to source, tier and confidence.

Not one model. A council I direct.

Four models advise. I set the brief, weigh the disagreement, and make the call.

Twenty years of decisions at institutional scale.

The rigour the largest international institutions demand, applied to the data their senior decisions actually depend on. This is the track record the AI work stands on.
