PROFILE
Jason Koch
Over four months, Josh Koch developed and enhanced capacity planning tools within the Netflix-Skunkworks/service-capacity-modeling repository. He built automated solutions for integrating AWS EC2 pricing data, generating instance family configurations, and expanding support for new AWS instance types, all aimed at improving cost modeling and capacity accuracy. Using Python, Jupyter Notebook, and JSON, Josh implemented deterministic data outputs, robust merge logic, and reproducible notebook-based estimators leveraging Erlang-C models. His work reduced manual configuration, improved automation reliability, and enabled data-driven decision-making for cloud infrastructure planning, demonstrating depth in backend development, data modeling, and cloud computing with a focus on maintainability.

May 1, 2025May 2025 monthly summary for Netflix-Skunkworks/service-capacity-modeling focusing on business value and technical achievements. Delivered automated AWS Instance Family Configuration Generator to improve capacity modeling. The tool automatically generates missing AWS instance family configurations, updates tests and instance family definitions to cover new instance types and performance characteristics, and broadens coverage of AWS hardware options. This automation reduces manual configuration, accelerates onboarding of new instance types, and increases accuracy of capacity planning across services.
