How I work
The way I work is constantly evolving. Here are some of the things I've been using to help create great designs.
AI assisted design
Claude has become a real design partner for me. I use it to poke holes in PRDs and spin up quick interactive prototypes on Vercel, and lately I've been playing with Paper and Magic Patterns to explore a bunch of different directions before committing to one.
Talking to people
Whether behind an espresso counter or a usability test, getting to know people is one of my favorite things to do. I love trying to figure out who a person is, where they come from, and anticipate what they might want in order to deliver better product experiences (or just to be a better friend!).
AI assisted development
My design work usually finds its way into the codebase. I've shipped design system PRs and built prototypes in React and Next.js. Working in code lets me get the details right instead of losing them in a handoff, and showing up to design reviews with something real has made me a much better collaborator with engineering.
