Video Edit for Keynote Speaker demo reel -showreel

I need a professional video editor to refine an already edited show reel for a keynote speaker. The goal is to showcase their speaking style.

Current show reel is more than 5 minutes.

Improvements needed:
- Better transitions
- Enhanced audio quality
- Adding text or graphics

Ideal candidates should have:
- Proficiency in modern video editing tools
- Experience with speaking reel enhancements
- Strong portfolio

This is a one-off project, but successful collaboration may lead to more work.

Please provide samples of your previous work.
