I have developed this real-time Chat web application using React.js, Node.js, Socket.io, MongoDB, and Express, where users can register themselves, and then send and receive real-time messages. I have also implemented the authentication due to which only registered users are able to use it.

I have developed a Node.js web application that can be used by different hospitals to maintain patients’ data. I have implemented redis caching to improve application performance and reduce database costs. Session authentication allows only authenticated users to access the portal.
