I would like to know if you could help me with something. What happens is I am developing a pool system, where I have 3 views: Admin, client and participant, but well, I have already done the logic for all three, and the administrator one already works but not entirely well and I would like to know if you could help me with that, I have already done all the designs (Frontend) and also implemented the logic (backend) but in the logic I do not know if it is entirely correct, as a general I would like to know if you could review my work and know if you could help me and when you would charge me for doing it. I am working in node.js with backend and frontend. here I share my folder so you can see it and find out if you can help me: https://drive.google.com/file/d/1k-GEO2rBKgMdaJm8CI9PnXuOruhzo_mc/view?usp=sharing
