Worked on the tgstation/TerraGov-Marine-Corps repository to enhance the player experience by expanding inventory options within the game’s vending machines. Delivered a focused backend update in DM, adding .41 AE and squash head ammunition types to the Valhalla and Crash vendor inventories. The implementation maintained code clarity by isolating changes to the vending inventory logic, supporting straightforward auditing and future rollbacks. This update established a foundation for ongoing improvements to the vendor system and in-game economy balancing. The work demonstrated backend development and game development skills, emphasizing maintainability and extensibility while providing a clear path for future inventory and vendor enhancements.
