Code audit

I have a code audit to do in the sense I am interested in doing a code review. You would need to come in and write your thoughts while checking if something will work rather or not.

The application was split into front-end and back-end (REST API). The front-end was written in React.js, Next.js, CSS. The backend (REST API) using Node.js, Express.js, Sequelize MySQL database

Development frameworks React.js, Next.js, Node.js, Express.js, CSS.

IMPORTANT: You don't need some out-of-the-box audit of every line. You need to review the structure of the code, take a moment to think, ask a few questions of the contractor and let me know how the code is evaluated.

I need this audit to be done by August 4 at the most. I assume that a person will need a few hours to do the audit.
