Testimonials

The time I was lucky enough to be Sergio's UI Lead allowed me to learn from a great professional who loves his work, which he carries out with great quality and an eye for the smallest detail. Beyond all this, which is a lot, he is a person who creates a great atmosphere, is a team player and is proactive. Any team that has him in its ranks will be very lucky.

Juan F. Molinera Product Design Lead in Orange

I worked with Sergio during his time at Papa John’s, and I would highlight his great sense of aesthetics and his perfectionism, which have been key to always delivering work at the highest level. He is very versatile, combining design projects for point-of-sale materials with web and social media work, always ensuring deadlines are met. He also has a positive, challenge-driven attitude that contributes to a good atmosphere on any team.
