I turn messy, unreliable data into clean, validated datasets and clear dashboards you can make decisions from.

Data analyst with a background in physics and mathematics, which means I treat data the way a scientist treats an experiment: validate it, question it, and only then draw conclusions.

I deliver freelance data-cleaning, analysis and dashboard work for my clients and review production Python code for correctness with Outlier (Scale AI). I'm especially comfortable with scientific and financial datasets, where correctness and validation actually matter.

I work in fixed-scope, fixed-price packages so you know exactly what you get and what it costs:

Also available on request: machine-learning modelling (classification, forecasting, segmentation) and LLM integration (API calls, prompt design, input/output parsing), scoped per project after a short conversation.

Years of teaching STEM gave me a second skill that matters as much as the technical one: I can explain a complex result to someone who isn't technical, clearly and without jargon.

Based in Sevilla; I work remotely across Spain and the EU.

Send me a short note about your dataset and I'll reply with a fixed-price quote and timeline within 24 hours.
