About Carlos

Data Analyst with hands-on experience turning data into clear decisions through dashboards, predictive models and data pipelines.


I work with Python, Power BI and SQL across industries including logistics, agri-food, environment and public health. I don't just build reports: I help clients understand what their data is telling them and what to do about it.

What I can help you with:

- Power BI dashboards tailored to your business, not generic templates.

- Predictive models for operational problems (regression, decision trees, classification).

- Turning complex datasets into actionable insights for non-technical stakeholders

Currently available for remote project-based work. I respond within 24 hours.
