As an experienced front-end and back-end developer, I feel confident that I have the right skill set to carry out your Chrome extension overhaul project. My proficiency in JavaScript is essential in making your website-checking function work seamlessly. With my ability to work with jQuery/Prototype and PHP, I can ensure the secure login process using OTP authentication efficiently.
It's necessary to work with databases, APIs, and server-side technologies during this upgrade process, and I'm adept at handling these components. Having worked on several similar extension projects, I am familiar with all the key aspects involved: modification of existing extensions or building new ones as per requirement.
I understand the urgency of your request and assure timely delivery of the completed extension within 2 days - the minimum time you asked for. Given my experience, skills, and adaptability, I believe we can create a robust, bug-free Chrome extension that aligns perfectly with your needs. Looking forward to having an opportunity to discuss this project in greater detail!
