Mathieu Lavoie
Senior Frontend Developer at Float. Previously Staff Frontend Developer at Shopify.
Eleven years crafting HTML, CSS and JavaScript — the last six focused on design systems: building one at LogMeIn, contributing to Polaris at Shopify, and now owning the design system on Float's Frontend Platform team. I care about frontend architecture, developer experience and accessibility.
