Developed and delivered the Smart Fridge Board Cargo Supply Pack feature for the Erikafox/Shiptest repository, expanding the in-game cargo system with a new purchasable pack priced at 500 credits. Focused on backend development and game development using DM, the work involved integrating the supply pack into existing cargo workflows while maintaining core gameplay balance. The implementation included data modeling for pack contents and crate types, ensuring compact storage and streamlined inventory management. Throughout the process, end-to-end feature delivery was established, covering design, integration, and validation, with commit traceability maintained and no regressions or major bugs introduced during the period.
