PROFILE
George Campbell
Graham Campbell contributed to the Netflix-Skunkworks/service-capacity-modeling repository by delivering targeted upgrades and refactors that improved reliability, maintainability, and compatibility. He migrated core models and serialization logic to Pydantic v2, updated interval type hints for greater flexibility, and enhanced disk sizing calculations to eliminate floating-point inaccuracies in capacity planning. Using Python and YAML, Graham introduced stricter type checking with mypy, modernized CI/CD workflows, and expanded code coverage tooling with Tox. His work addressed both feature development and bug fixes, ensuring the codebase remained robust, forward-compatible, and easier to maintain as dependencies and platform requirements evolved.

Mar 1, 2025March 2025 performance summary for Netflix-Skunkworks/service-capacity-modeling: Focused on accuracy and reliability of capacity planning in the RDS modeling workflow. Delivered a critical bug fix that eliminates float-based inaccuracies in disk-space estimation, thereby improving resource provisioning decisions and reducing risk of over- or under-provisioning. Key technical approach: applied math.ceil to the computed disk space (size_gib), using the formula x * 1.2, ensuring the required disk space is an integer. Commit reference: cdec66ce723fe2fd2d4695e439668a39753caa22. This work strengthens capacity planning and reliability across deployments.
