I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, screenshots and copywriting, and I can assist with frontend development where needed. My background as a tech startup founder and full stack developer helps me create practical design solutions that balance usability, aesthetics, development effort and performance. I work to fixed price quotes when projects are self-contained.

The best live example of my work is Checkbot (https://www.checkbot.io/), a browser extension that tests websites for SEO, speed and performance problems. The entire project is my own work including coding the extension itself, UX/UI design, website design (the homepage is optimised to load in 0.7 seconds, 0.3MB data transferred), website copy, and website articles on web best practices.
