Project that helps to improve buyer/supplier relationship management using data analysis and measuring user experience by collection feedback.
I came to project not from beginning, so at first time reworked a bit structure to switch to HapiJS server infrastructure, added structure of unit tests to have good coverage. Then worked on business logic of the application, as well as front-end part of project. One of the challenging features visible for all users was implementation export to PowerPoint slides of analytic data with charts, tables, dynamic pictures and so on. Also worked a lot to improve Angular modules to have good performance across all main browsers, including old versions of IE, on big sets of data.
