UI / UX Designer

I design the moments where products lose people.

A paywall. A first visit. An ER intake form. An intruder at the door. Five case studies about the highest-pressure screens in a product, and what changes when you get them right.

About

Hi, I'm Joaquin — a UofT graduate (High Distinction) and UI/UX designer who believes fun is equal to success.

I love turning messy problems into clean, intuitive interfaces, with a background that blends Figma-driven UI/UX work, multimedia production, and a healthy obsession for tech (the kind that has me self-hosting services and tinkering with Linux on the weekends).

I bring both a creator's eye and a problem-solver's mindset to every project — whether that's a 53-test-case usability study or a Lottie animation handoff to engineering.
