Dawid Krajewski

Co-founded Sherlo with Michał Ziółkowski.

Dawid has been a front-end developer since 2012, when he started building client web projects at Dige for Toyota, Santander Bank and Onet.pl. Mostly HTML and CSS, some JavaScript. That is where the habit of caring about how a UI actually renders started.

In 2015 he joined home.pl, where he led the front-end of a design system built from scratch with the design and backend teams: a theme-swappable React component library where changing one config file restyles the whole product. The same codebase shipped across brands. Six years there taught him how easily a UI drifts out of sync at that scale, and how hard that kind of change is to catch by hand once more than one product depends on the same code.

In 2022 he co-founded Devine, and Sherlo grew out of it. Today he works hands-on across the whole product: code, customer conversations, and everything in between.
