Analytics and AI leadership

I build AI agents that make operating decisions and carry them out, on data infrastructure solid enough to trust them with the call. Today they run a six-country retail operation. The same problem waits in every industry with a digital transformation to deliver.

What I build

Portable across industries

Agents that decide, not suggest

The first ones grouped hundreds of locations by the shape of their demand and pushed the answer straight into execution. Work that used to be a monthly spreadsheet now runs on its own, and every decision it makes is logged.

Return without new spending

Most of the gain came from moving assets that were already paid for to where they earn. Any business with inventory, capacity or people sitting in the wrong place has this same problem, whatever it sells.

The plumbing underneath

Agents are only as good as what they read. A cloud warehouse, governed master data and automated planning came first. That order is not optional, and it is where most AI programmes quietly fail.

Running in production, past the pilot

These agents cleared the pilot stage and now run inside the weekly operating cycle, with named owners on each decision. Their output lands in the same numbers the business already reports every month. Most AI work I have watched die, died before this point.

Every claim gets a control group

Saying an AI project worked is easy. I compare the sites that got the change against similar ones deliberately left alone, so the gap between the two lines is the part that holds up when a board asks how we know.

Difference-in-differences, reconciled against the warehouse before anything leaves the team.

How to read it

  • Where the change was made
  • Comparable sites, untouched
  • The day it started
  • Same starting point
changed untouched

Method

Sailing directions

Three notes on how this work is actually done. No case studies and no client names, because the method is the part that travels.

Where I have done it

Fifteen years
2025 to now

Director of Analytics Retail, six countries · Empresas ADOC

I run analytics across six countries and sit on the executive committee, reporting to the board each quarter. Planning, allocation, S&OP, data governance and the agent work above all report here.

2020-2025

Building the data function from scratch Empresas ADOC

I arrived as a BI specialist and left the role as manager. In between: the cloud warehouse the company now runs on, reporting that stopped being manual, and delivery times cut from two and a half months to one.

2011-2020

Airline operations analytics Avianca Holdings

Nine years on flight performance and fuel. I automated analysis that took twelve hours down to one, and found $700K a year in savings validating how fuel was actually used. Different industry, same method.
