Hello,

My name is Sergio — most places on the internet, sgualda. I design and build digital products, based in Barcelona, originally from Almeria (southern Spain).

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 logic behind how things behaved. That same mindset is what led me into product design.

The road here was not 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 does not 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.
