Hi there , Satvik here to help you out , As I have seen you have not mentioned much about the project , So , we can discuss further details in the chat only. And you can see about me in my portfolio , I have done similar node.js backend specific works , I also do have made complete backend with node.js and express for my clients , So , if you feel ok , then we can start.
