Game Director · Founder of Tappatapps · Barcelona

15 years making mobile games. Now making them with AI.

I run Tappatapps, a Barcelona studio using AI to build mobile games with heart, style and staying power. Before that I led and designed games at Sandsoft, Tripledot, Scopely, Social Point and DeNA.

About

Designer, director, founder

I design systems, economies and UX that make games feel good in the hand, and lead the teams that ship them. At Tappatapps I'm also building the company itself: funding, production and tooling.
