Gmail Auth Web App with User Interaction

I'm looking for a skilled React developer to create a web application with the following features:
- Gmail account login using Firebase Authentication.
- A user profile section where personal and bank account details can be updated.
- Interaction with my YouTube playlist: users can click to play random videos and comment.
- A comment counting and storage system.
- An auto-level upgrade system for users based on their comment count.

Further project details will be shared upon confirmation of the deal. Ideal candidates should have:
- Extensive experience in React and web development.
- Familiarity with Firebase Authentication.
- Previous experience with YouTube API integration is a plus.
- Strong understanding of user interface design.
