Callum Prasser focused on maintaining the stability of the Ten10-Academy-Team/Foundations-of-tech repository by addressing a content integrity issue during November 2025. He reverted an unintended modification to a text file, restoring the original course material and ensuring consistency across downstream modules. Using strong git discipline and text editing skills, Callum provided a clear audit trail through precise commit messages and thorough documentation. Although no new features were introduced, his work centered on bug remediation and code hygiene, supporting reliable content delivery. The technical approach relied on version control best practices and careful management of text-based resources to prevent content drift.
