Shaka Player Customization

I'm looking for a skilled developer to fix UI bugs and customize the Shaka Player. The player should function seamlessly across all major devices and browsers, including Windows, iPad, iPhone, and Android devices.

Key Requirements:
- Fix bugs where UI sounds are inconsistent and unify volume and playback controls across devices.
- Modify the HLS #EXT-X-PROGRAM-DATE-TIME tag implementation:
- Change slider display from real-time (HHMMSS) to date/time format (YYMMDDHHMMSS).
- Enable playback by specifying start and stop date/time, with looping functionality.
- Create built-in extensions and UI operations for the above features.
- Allow external API usage for date and time specifications.

Ideal Skills and Experience:
- Proficiency in Shaka Player
- Strong front-end development skills
- Experience with HLS and UI/UX design
- Familiarity with cross-platform testing and debugging

Please provide examples of similar work done.
