Developed and delivered a new feature for the OpenTTD/OpenTTD repository, enhancing the vehicle information display by introducing a maximum reliability metric. This addition required extending both the user interface and the underlying data model to present maximum reliability alongside existing reliability and breakdown statistics, providing users with more comprehensive data for vehicle maintenance decisions. The work was implemented using C++ and focused on game development and UI development principles, ensuring seamless integration with the existing system. Over the course of one month, the developer concentrated on this single feature, demonstrating depth in both technical execution and understanding of user needs.
