Shirt Magic - Printing Company - Main Developer

Designer Project description This project is basically a platform for shops and artists that are engaged into cloth printing business. This was a very interesting project for me because I started it when it was just a sketch, and lead it to a competitive platform that was on the first page of google search. What I like about this project is the fact that we build a system with a large set of tools by using a wide range of modern technologies, and we were able to create some superiority over competitors. And I consider this project a good "self grow" step in my professional carrier.
