During a two-month period, Nick Humphry contributed to the isaacphysics/isaac-cdn repository by delivering two new PDF resources to enhance teacher-facing materials. He added a CPD resource and an event asset, each integrated into the CDN with careful attention to file management and version control. Using Git for repository management and working with binary assets, Nick ensured that both resources were discoverable and accessible for educators and event participants. While the work focused on asset delivery rather than codebase changes or bug fixes, it demonstrated a methodical approach to resource organization and adherence to established asset management conventions.
