Looking for a developer to update and fix bugs in my nodejs and express based application

Here is my nodejs and express based chat application [login to view URL] Which is a roulette chat application, which connects strangers to find other people who connected through the chat application. It contains almost all functions, but there is few bugs, which is not reliable and user friendly. >> Can't connect more than 10+ realtime users, app crashes and keep getting reconnected to socket. could be some socket based issue. [login to view URL] getting crashed and re connected. >> Need male and female gender identification option, so it will be easy to find the other stranger is a male or female before start chatting with them. >> User country information. Getting users IP and use API to get the location and show users flag while chatting. Will explain more about this job in private message or through zoom call with share sharing to make it more detail to get things understand before getting into job. If there is a need of increasing the budget after discussion, sure i can pay extra $$ for the work you do. SO the $200 is not the final price for this job work.
