Antidetect Browser with Customizable JavaScript

I'm looking for a skilled developer who can create a feature-rich antidetect browser that can operate on Windows and Mac. The project requires the following:

- Antidetect Browser: The primary requirement is to have a fully functional antidetect browser that can effectively mask user information and browsing behavior. This is crucial for the success of the project.

- Customizable JavaScript: The ability to randomize the JavaScript loaded on the go, on each visit, is a key aspect of this project. This feature is very important to me, so it's essential that it's implemented seamlessly.

- Third-Party Service Integration: The project does not require integration with any third-party services, such as proxy or VPN services, or automation tools. The focus here is on creating a robust antidetect browser with customizable JavaScript.

Ideal Skills and Experience:

- Extensive experience in developing browsers and browser extensions
- Proficiency in working with Windows and Mac operating systems
- Strong knowledge of JavaScript and its manipulation
- Familiarity with antidetect techniques and implementation
- Ability to work autonomously and deliver a high-quality, fully functioning product

If you possess the skills and experience required for this project, I look forward to reviewing your proposal.
