Most data problems are language problems.

I know this because I spent years studying language before I ever wrote a pipeline. My PhD is in Hispanic Linguistics — I was trained to notice how organizations use words, how context changes meaning, and how people talk past each other while believing they're communicating. It turns out that's exactly the diagnostic skill you need when a company's data infrastructure isn't working.

After my doctorate, I moved into data engineering and ML consulting. I've built cloud pipelines in Microsoft Fabric, implemented LLM and RAG systems for companies that couldn't yet hire in-house AI teams, and designed decision tools for leadership at firms in New York, St. Louis, and across Spain.

What I bring that most technical consultants don't: I can walk into a room, listen to how a team talks about their data problem, and tell you in thirty minutes whether it's a technical problem, a governance problem, or a communication problem — and which one to fix first.

Most engagements start small and grow when they're useful.

Entry point

Data Infrastructure Review

A fast, focused look at your current data setup — where things are breaking, where value is being left on the table, and what to fix first. Plain-language debrief your leadership can act on.

Good if you're AI-curious but not sure what you actually need.

Ongoing

AI Transformation Retainer

Monthly: architecture choices, team guidance, vendor evaluation, keeping ML initiatives honest. A fractional CDO without the overhead of a full hire.

Good if you're executing post-audit and need senior judgment in the room.

Monthly · 1–2 clients at a time

Executive Visibility
National Retailer

Reporting was built for analysts, not operators. I rebuilt the decision layer: a dashboard correlating review data and sales performance across locations, readable in thirty seconds by the people who actually needed to act on it.

Client Experience Gaps
Wealth Management Firm

I ran a user research phase first — because the mental model mattered as much as the visualization — then surfaced the gaps between what advisors believed clients felt and what the data actually showed.

Power BI · Survey analysis · Qualitative research

App Adoption
Internal Tool Redesign

The assumption was a training problem. The reality was a language problem: the interface used terms that didn't match how field workers thought about their jobs. I identified the friction and redesigned the key interface. Adoption increased measurably.

Let's talk.

Whether you're scoping a project, figuring out where to start, or just want a first conversation with no agenda — I'm easy to reach.

I work with companies in Spain and the US, typically 50–300 people, at the point where AI feels urgent but the infrastructure isn't ready.
