Want to understand web application code by code made in Angular and Java

Hello, I'm looking for a freelancer to help me understand a web application code written with Angular and Java. Specifically, I'm looking for a freelancer who can do a full code review in order to help me gain an understanding of the existing code. My team has an advanced level of experience with Angular and Java, so the freelancer needs to have an equally advanced level of knowledge. So if you think you've got the expertise necessary to give me the insights I need to understand this piece of code, get in touch!
