I'm Jules Simplicio.
I design and develop digital products.

I focus on user experience, user interfaces, design systems, and on product and software development.


I was born and raised in São Paulo, Brazil. I currently live with my partner and our two cats in the Humboldt Park neighborhood of Chicago. In my spare time, you can find me spinning house music records, skateboarding, playing the guitar, and building personal apps.

My pronouns are they/them/theirs.

Jules Simplicio


I participate in dialogues about community and design.

Friends in tech say...

In every instance, they provided thoughtful, specific feedback and truly cared about making it a growth experience for the students they worked with... Their dedication to helping the design community grow and flourish in Chicago is a prime example for our students, our other mentors and critics, and designers across the city.

Jules was an empathetic mentor who got to know me as a person so that they could guide me towards opportunities that fit with my personal and professional objectives. Jules' thoughtful advice and wealth of industry knowledge was invaluable to me as a young designer!
