I had opportunity to work on entire web app design for the new online payment system Storage.Money launched in 2016. Working with a client I designed the app look and logic accordingly to the clients requirements. For better understanding and planing phase, I developed a fully intractable app prototype based on my template. The prototype features a programmed logic with input validation and non linear interaction, wich basically simulate a real mobile app behavior. In the next phase I worked closely with development team and was providing them all graphics and templates needed.
You can test the app prototypes online: English language / Russian language
or watch a demo video below.
