About

Sean Kerwin

I’m Sean Kerwin, an engineer with over 15 years building for the web. Front-end is my speciality, React, Next.js and TypeScript in particular, though I don’t limit myself to it. I care about performance, accessibility, and interfaces that feel good to use.

Right now I’m a Senior Engineer at Deskpro, working on the helpdesk product. Before that I spent time at Toolstation and a long stretch at T-Shirt and Sons, where I worked across the whole stack.

Away from the keyboard you’ll usually find me with my family or out on a motorbike.
