My Design Process · 5 min
Graduated from design school and landed my first role as a junior UI designer at a small agency in Porto. Fell in love with product design.
Took the leap to freelance work. Moved to Lisbon, built my first portfolio, and started working with startups across Europe.
Designed the complete brand identity for Lumina Labs, a Series A startup. The project won recognition at the European Design Awards.
Crossed 100 completed projects. Built long-term relationships with repeat clients and expanded into product strategy consulting.
Began focusing on scalable design systems and component libraries. Published my first case study series and started mentoring junior designers.
