About Andrés

If your company still relies on Excel spreadsheets for critical decision-making, or your current reporting system doesn't scale with the business, I can help.

I am a freelance consultant specializing in Power BI and Power Platform, with 9 years of experience combining SME and IBEX company environments. I support companies looking to modernize their analytics and automate processes without the complexities — or cost — of a poorly sized enterprise project.

Experience in SMEs and mid-market:

5 years at the restaurant group Kilómetros de Pizza, where I led the adoption of the Microsoft stack (Power BI + Power Platform) from scratch.
2 years at Seguros Pelayo, managing Power Platform projects on Dataverse and integrations with generative AI tools.

Enterprise track record:

5 years with Meliá Hotels, Repsol, and Prosegur on large-volume projects: modern Fabric/DirectLake architectures, advanced semantic models, dynamic RLS/OLS, ALM/CI/CD, and Premium capacity administration.

This means I apply professional standards (governance, scalability, security) at the scale your company truly needs, without over-engineering or unnecessary licenses.

My three main services:

1. Power BI or Power Platform implementation from scratch — for companies moving away from Excel.

2. Audit and optimization — for existing Power BI/Power Platform ecosystems that are underperforming, not scaling, or poorly governed.

3. Technical mentoring for internal teams — for companies with junior/mid-level developers who need a recurring senior reference.

I work remotely from Madrid (also hybrid if the office is in Madrid). If you have a project or a question, write to me: I respond within 24 business hours.
