YouTube Schema Design in 72 Hours

I am looking for a highly skilled and experienced tech wizard with deep knowledge and understanding of ER Diagrams and database schemas. Your primary task would be to research YouTube meticulously and design a comprehensive schema that encapsulates its inherent functionality. Although specific features for the schema design haven't been pinpointed, think broadly and strategically, encompassing aspects such as user management, product inventory, or order tracking. This is an urgent task, and the ideal turnaround time is within 2-3 days. Show me that you have the skills and experience to get this job done in the time limit and you've got the job. Example project included. Need something similar for any leading platform of your choice (Youtube is my suggestion).
