Developed and delivered a Linux-specific video playback sleep inhibition feature for the open-ani/animeko repository, ensuring uninterrupted media playback by integrating systemd inhibitors within a Kotlin-based desktop application. The implementation replaced an erroneous DBus approach, resulting in a more stable and maintainable solution tailored for Linux environments. Throughout the process, code quality was enhanced by refining naming conventions and addressing code-review feedback, which improved clarity and future extensibility. This work not only reduced user friction by preventing unwanted system sleep during playback but also established a cleaner codebase, laying the groundwork for broader cross-distribution support and ongoing maintainability.
