Worked on the esmini/esmini repository to enhance simulation reliability and code maintainability using C++ and code refactoring techniques. Addressed a bug in the ghost trailer naming logic by ensuring names were cleared before reassignment, which resolved duplicate naming issues within the simulation environment. Focused on improving code readability and maintainability in ScenarioEngine.cpp by performing lint-level cleanups and adjusting whitespace, while preserving existing functionality. These efforts reinforced code quality and consistency across critical components, reducing the risk of future defects and supporting easier onboarding for new contributors. The work demonstrated a methodical approach to simulation software development and quality assurance.
