Hi, I have experience building robust Nodejs APIs with Express, Sql and MongoDB. I have developed different kind of APIs for different purposes, for example : Authentication, Scraping, ECommerce applications, etc. I have also good working knowledge with SocketIO to develop Chat based Apps. SocketIO is considereably better than WebSockets ( although SocketIO sometimes uses WebSockets in the background) the reasons being proxy issues, too much of redundant code, etc.
I'll be happy to work on this and of course to hear from you!
Thank you!
