Hi,sir. Thanks for taking your valuable time for reviewing my proposal.I'm a senior developer with over 10 years of experience. I think I can be a candidate for your project. If you can give me your project, I'll do my best to complete it in a short time.
I am confident of your project - Manage a YOUTUBE Channel (Yoga Videos) - (uploading and optimizing videos).
And I have been very familiar with skills such as Marketing, Social Media Management, YouTube, SEO, Social Media Marketing and so on.
