Frontend Developer


About me

Hi! I'm a front end developer with over 4 years' experience of building for the web. I have designed and built new features, functionality and experiences, contributed to design systems and maintained pattern libraries.

Most of my programming experience is in JavaScript, React, Typescript, HTML and CSS. I have worked on sites using Gatsby + Contentful, and currently building projects in Next + Sanity with Tailwind for styling. I use Jest and RTL for testing, and CircleCI for continuous integration. I mostly host on Netlify.

I have a total of 9 years' experience in digital roles, spanning web development, UX and usability, design and analytics. I have therefore built up a broad skill set that allows me to approach dev work with a strong understanding of the user, and work well in cross-functional teams.
