I was asked to create a UI as well as code the front-end of a web-based service that provided calculations for amino acid values on a large database of foods. The UI had to be mobile friendly, cater towards iPhone users, but still be accessible and easy to use from a desktop computer. I also coded the front-end and did all the visual work, including the CSS and all the JavaScript that run the app. The app is live at http://howmuchphe.org
