Hi, I'm Dan.

I started in graphic and editorial design, moved into UX and UI, led design teams and founded my own products. That path is why I work end to end: I have sold the project, run the workshop, drawn the screens and, lately, shipped the code with AI as my build partner.

My specialty is gamification, engagement and learning experiences, the part of a product that makes people come back. I'm finishing two postgraduate specializations, in Games & Gamification in Education and in Corporate Pedagogy.
