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.
