Collaborative participation in the development of a survey system for Metropolitan Touring. The system allowed the company's customers to complete satisfaction surveys, as well as request customer service tickets. Work primarily focused on various Frontend screens of the system using React/Typescript with proprietary libraries such as Syncfusion Data Grid and KendoReact by Telerik. Together with jlgranda.com, we managed to optimize the performance of the already overloaded application and unified criteria for handling OData (Open Data Protocol) requests and their impact on rendering. Without a doubt, this is the largest codebase project I have been involved in to date, and the one that has taught me the most about teamwork, the importance of documentation, and coding standards.
