hi, i'm joão guilherme, but you can call me jem!
i'm a ux/ui designer based in são paulo. i started out in graphic design and worked for over 5 years in agencies, freelance gigs, and even created an nft project. eventually, i transitioned into ux, where i found a way to combine aesthetics and functionality in a way that made much more sense to me.
i'm driven by curiosity and genuinely dedicated to everything i set out to do. i enjoy playing challenging games, drinking iced tea, always have music playing, and i say “pss pss” to every cat i see on the street.

i made this project to practice my html, css, js and because customizing your character is just too tempting.
as you explore my portfolio, you'll collect coins that can be exchanged for stylish hats.
hope you have fun, enjoy the journey!
ps: it works best with sound on.
