Selinium Automation - Browser Automation

We are looking for browser automation experts who could help us design and develop automation bots to perform certain complex browser tasks.

Following is an example of one such task:

Login to gmail accounts from the browser with the credentials (user/pass/secondary id),
Perform certain actions such as:
Read the emails based on certain rules
Move the emails from spam folder to inbox
Mark the emails as important
Lot of other actions to be performed based on the required rules/logic.

A list of a few hundred gmail accounts will be maintained for simultaneous usage based on the requirement.
This task has to be done using several simultaneous threads and proxies with appropriate browser fingerprints, with ZERO fingerprint leakage.
Thorough knowledge on browser fingerprints is very important.
Ability to maintain the same fingerprint and browser cookies for repeat access/without the need to login every time.
Human like mouse movements & keyboard activity.
All activity should be real human like and bot behaviour must not be identifiable.
Scalability of the product, use of several simultaneous sessions with different gmail accounts, use of proxies, correct updated browser fingerprints, cookies, ability to maintain a unique fingerprint for each email account and cookies for repeat access/without the need to login every time, use of third party apis wherever required, etc are some of the key requirements.
These are just some of the requirements.

We have many automation projects in the pipeline, If you can help us develop such automation tools, please feel free to connect.

PS: Only connect if you have expertise in automation.
