Worked on the isaacphysics/isaac-cdn repository to deliver a targeted content refresh for the STEM SMART biology curriculum, focusing on updating Week 3 resources. The approach centered on disciplined file management, explicitly removing an outdated PDF and adding a new resource through traceable, auditable commits. This process ensured that curriculum assets remained current and aligned with the Phase One roadmap, reducing the risk of user confusion and supporting reliable content delivery. Leveraging skills in content creation and educational resource development, the work maintained asset lifecycle integrity and compliance, while ensuring stability by introducing new features without introducing bugs or regressions.
