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 AWS instance family configuration generators and integrated EC2 pricing data, using Python and Jupyter Notebook to streamline data loading, deterministic output, and performance modeling. His work included implementing headroom estimation tooling based on Erlang-C models, expanding support for new AWS instance types, and refining data formatting for automation reliability. By focusing on API integration, infrastructure as code, and robust testing, Josh improved the accuracy and scalability of capacity modeling, reducing manual effort and enabling more data-driven, reproducible infrastructure decisions.
