I am writing to you in response to your project request for a freelancer to build a javascript library that integrates OAuth Flows and SellerCentral APIS. I believe that my experience and qualifications make me an ideal candidate to fulfill this project.
I am an experienced web developer with expertise in AWS, SellerCentral, and OAuth Flows. I am confident that I can create a javascript library that integrates OAuth Flows and SellerCentral APIS into your website. The deliverable will be a JS file and script to manage session. If there is a valid token then have it available as a variable to consume APIS, if not, then request for login credentials using automatic Login AWS form. As per your request, I will ensure that the library works on regular javascript without the use of any frameworks such as Angular, React, etc.
I understand the importance of meeting project deadlines and I am well-equipped with the necessary skills to develop a high-quality javascript library.
