Why Figma Beats Sketch

For a long time, the biggest players in the UI design market were Adobe (Photoshop, Illustrator) and Sketch. Both of these tools aren't very collaborative.

Me

How I work, what I read, who I cheer for.

I work fast on purpose. Speed isn't the opposite of care — it's what buys the time to collaborate, iterate, and try the version no one asked for. The faster I can put something in front of someone, the more shots I get at making it right.

Most of what I do at TRY sits in the seam between design and engineering, which is where the interesting work usually is. I've been writing React since I built my first site nearly ten years ago. Still my favorite, and nothing else lets me move faster. For styling I usually reach for Tailwind.

Sometimes I write about the work too — usually when something is bothering me about how it's done.

When I close the laptop, I'm hunting Unknown Pleasures in Stockholm's vinyl shops, cheering for Änglarna (IFK Göteborg) in Allsvenskan and McLaren in F1, and usually halfway through more books than I should be — currently Great Expectations by Charles Dickens, and recently read Breakfast of Champions by Kurt Vonnegut and How to Build a Car: The Autobiography of the World’s Greatest Formula 1 Designer by Adrian Newey.
