About

A practitioner who shows his work

I'm a data scientist, educator, and technical writer from Barcelona and currently based in Rotterdam. I consult on Data Analytics, DataViz and AI, create content that makes complex AI and data concepts click, and teach data science to professionals and students worldwide.

With a bachelor in Engineering Physics (UPC) and a master in Intelligent Interactive Systems (UPF), I combine technical rigour with clear communication. If you need a Data Science project built, a data concept explained, a course designed, or technical articles written, I deliver work people can actually use.

Associate Professor, Big Data Masters — Universidad de Navarra

How I work with you

01

databites Consult

I help institutions and research organisations make better decisions with their own data and GenAI. Three ways to work together:

Workshop (1 day): your team analyses its own data with GenAI and presents it to the people who decide

Pilot (6 to 8 weeks): one real decision answered, with a clear visual result and a tool you keep

Ongoing support: the tool kept up to date and new questions answered every month
