Developed a live cluster CPU utilization–based enhancement for the Kafka capacity model in the Netflix-Skunkworks/service-capacity-modeling repository. This work integrated real-time cluster CPU data into the core estimation process, allowing the model to compute required resources more accurately and fall back to previous calculations when live data was unavailable. The implementation introduced a standardized function for handling CPU targets and refactored the estimation logic to prioritize live data. Comprehensive testing was added to validate the new workflow. Leveraged Python and Java, applying skills in capacity planning, performance analysis, and system modeling to improve resource provisioning and operational reliability.

March 2025: Delivered a live cluster CPU utilization–based enhancement to the Kafka capacity model in Netflix-Skunkworks/service-capacity-modeling. The model now uses current cluster CPU utilization to compute needed cores, with a fallback to the previous calculation when live data is unavailable. Introduced a target_cpu_utilzation function and updated the estimation logic to prioritize live data. Added test_plan_certain to validate the new behavior. This work improves capacity planning accuracy and responsiveness, enabling better resource provisioning, cost efficiency, and reliability in dynamic environments. Demonstrated strengths in data-driven modeling, live data integration, test planning, and clean refactoring.
