We worked on premium wall art e-commerce platform with product editor,where one of our main tasks was the development of REST API that assured direct communication between project ERP and printing machines as well as other custom features. Shipment orders and product prices are dynamic and get calculated depending on users location (different logic for each country) thus printing and shipping their products all around the globe. How cool is that? :) Additionally, to building all backend functionality, we performed special performance optimization for the whole project, optimizing both - page load time and reducing homepage queries to a minimum. And on top of that, all project images were processed through complicated imagemagic scripts, that allowed to skew them in a very stylish way. The project proved to be a real challenge for us as the business. Requirements were growing as the project evolved and we had to do constant updates while still keeping project and code clean. Challenge successful!
