I have a full-stack software with backend in Nodejs and front-end in Typescript/React. The description of the code is provided in the section below. The code is working but I want to do 2 things

(1)Do an end-to-end testing and validation of all the features described below (the code was developed by multiple developers over a period of time, hence I want an integrated test). Ideally, I want to create some kind of automated test routine, that can confirm each and every step of the code before I make a release for customers.

(2) There are a few known issues / bugs that I want to get fixed also. I have mentioned them in the description below

For someone who know full stack development and debugging, it should be a simple short-term task. You should also have a good working knowledge of AWS and basic Generative AI API calling functions.

Important Note: This is a short-duration and time critical project. If you do not have all the skills and cannot complete the entire project, please do not apply. I can only pay for the full and complete project.

Note 2: if you want to see the existing code, please send me your Github handle via Upwork messaging and I will add you as a collaborator
