I do all things Frontend and would love to bring my expertise to your team. I enjoy working on product teams and value diversity, trust, and gentle but effective communication. I offer 7 years of relevant hands-on experience in the industry. During this time I built robust, well-tested frontends. Always with the end-user experience, performance, and accessibility in mind. These days I mostly focus on React but I'm happy to work with other things as well.
