This project was a refactor of existing fleet management software which included a vast increase of capabilities. This application comes with a separately built mobile UI which had to compress a lot of last second data to fleet managers. The application stores and analyzes wide ranges of vehicle behavior to distill down to quickly accessible kpis on both drivers and vehicles separately. The application relied heavily on geo data which can be imperfect and requires a UI layer to indicate data that is assumed along with data that is known. My contributions to this project included simplifying the data collected so managers can quickly skim for problems and search for details.
