Curious by nature. Designer by trade. Builder by choice.
I’m Mario, a Colombian digital designer and builder currently based in Spain.
For more than 10 years, I’ve worked with both early-stage startups and global companies, designing digital products for teams at Klarna, Wolt, Walmart, and beyond. I enjoy the whole journey: figuring out what should exist, turning vague ideas into something tangible, and pushing the details until the product feels just right.
I’m also the kind of person who rarely leaves design alone. I’m learning to code, experimenting with AI, building apps, and generally finding new ways to turn ideas into things that actually work.
Away from the screen, I collect things, drink a lot of coffee, follow football, play videogames, go to the gym, ride my bike, and occasionally convince myself that trying a complicated new recipe is a good idea.
