Redi Kustiwa developed a user quota storage and retrieval feature for the sBeacon-BGSi repository, focusing on scalable quota management through API endpoints and persistent storage. Using Python and AWS Lambda, Redi designed and implemented a DynamoDB data model called Quota, along with quota_function.py to handle POST and GET operations for storing, updating, and retrieving per-user quota data. This work established a foundation for future quota-based controls, improving resource governance and cost management within the system. The feature was delivered end-to-end, demonstrating depth in backend development, serverless architecture, and API design, with minor maintenance tasks ensuring ongoing stability and reliability.
