Meet our member Henric! He’s quietly making sure your favorite websites don’t break without anyone noticing 🖥️🔍 Henric Persson
Henric is co founder of Happo, a visual regression and accessibility testing tool he’s been building for the past decade. It’s completely bootstrapped, with Henric and his US co founder Joe running it as a two-person operation💪
Some of the world’s biggest products quietly lean on Happo to catch the pixel that shifted or the button that lost its contrast. Airbnb, Pinterest, Patreon, Plaid and Monzo are among them 📐✨
When he’s not debugging a stubborn Kubernetes deployment at 11pm, you’ll probably find him chasing a scratch handicap on the golf course ⛳ or here at Knackeriet, coffee in hand, quietly getting things done.
