Developed an asynchronous cache pruning mechanism for the tw93/Mole repository, focusing on reclaiming disk space by removing expired cache files in the background. The solution leveraged Go’s concurrency features, utilizing goroutines to ensure that pruning operations were non-blocking and safe during cache reads. By basing expiry checks on file modification time rather than content decoding, the approach minimized I/O overhead and improved overall performance. The implementation supported both TUI and JSON modes, ensuring consistent behavior across interactive and automated workflows. This work demonstrated backend development skills in Go, with attention to filesystem I/O optimization and cross-mode integration for reliability.
