Sergio, Product Designer in Barcelona

Hey, I'm Sergio Gualda

Based in Barcelona, originally from Almería.



I’ve always been drawn to understanding how things could be different. As a kid, I was more interested in possibilities than instructions. Fascinated by the invisible logic behind how things behaved. That same mindset is what led me into product design.



The road here wasn’t exactly planned. I started out learning how to build things with code. Later, I got into visual work and communication. Somewhere along the way, I realized what I really cared about was creating things that make sense to people, things that feel good to use and solve real problems.



Now I help founders and companies turn messy ideas into clear, usable products. I care about flow, simplicity, and making digital experiences feel effortless. If someone doesn't have to think too hard while using something, I’ve done my job right.



I believe in being honest, staying curious, and not taking things too seriously. I enjoy working with people who are passionate, open to experimenting (and messing up), and who see feedback as a way to get better, not as something personal. Bonus points if you can make me laugh in the process.



Let’s build things that matter and enjoy the ride while we’re at it.

Outside of work

Nature clears my head, new cities inspire me and conversations with friends in the sun keep me alive. I like trying new things, sometimes failing, sometimes obsessing over random topics. Running, books, films, and slow coffee give me stillness.

For me, creativity doesn’t just come from work. It comes from everyday experiences that help me see the world differently.
