During May 2025, Ren developed and delivered the Smart Fridge Board Cargo Supply Pack feature for the Erikafox/Shiptest repository, expanding the in-game cargo system. This backend feature introduced a purchasable supply pack priced at 500 credits, including its contents and crate type, providing a compact storage solution that preserved core gameplay balance. Ren’s work involved backend development and data modeling in DM, integrating the new pack into the existing cargo workflow and economy without introducing regressions. Although no major bugs were fixed during this period, the feature demonstrated end-to-end delivery, from design through integration and validation within the game’s infrastructure.
