During April 2025, contributed to the alphauslabs/blueapi repository by developing a new Container Cost Usage API endpoint, GetContainerCostUsage, designed to enhance visibility into container cost and usage metrics. Leveraging Protocol Buffers and gRPC, implemented features such as filtering, grouping, and time granularity, enabling users to analyze cost data with greater precision. The work included adding CPU and memory utilization metrics, refining request and response models, and adjusting API paths for consistency. This API development effort supports improved cost governance and optimization by providing granular insights, and demonstrates a methodical approach to evolving data models and service interfaces.
