why work with me

i believe great design starts with understanding. when we work together, you’re not just hiring a designer — you’re partnering with someone who cares about your product, your audience, and your goals. i combine strategy, design, and development to build brands and websites that truly make an impact.

When I'm Not Designing

you’ll find me producing electronic music, exploring barcelona’s creative scene, or sketching new ideas over a good espresso. i’m inspired by architecture, fashion, and moments that blend design, rhythm, and emotion.
