I was part of a team in charge of the development of a mobile app for Solar Panel installers. In which I've been involved in the next activities:- I worked on modifying the HTML and CSS of several pages of the app to increase the target of mobile devices with bigger screens.- I worked on research to identify the steps to commission the hardware through an iOS and Android simulator. Its purpose is to help QA and developers to test the app on every device needed without having to depend on the physical device, this research was first intended to help test several changes on iPad devices.- I helped improve the user experience by modifying several pages of the app to allow the user to interact with buttons without scrolling to the end of the page.- I proposed and implemented the redesign of a screen that used to be complex and redundant to the users, now this screen allows the user easily and more intuitively to interact with.- I replaced a tool that cost the client a hundred thousand dollars a year with a cheaper one that covers all the needs as the expensive does.
