an aggregation of my web backends

Serves chat messages to all chat clients that request them. Allows clients to post new messages and efficiently ping to see if a new message was posted.

Shows to user chat messages pulled from server. Can also post a new message. Has quite efficient implementation of pinging (listening for) new messages that might have been posted.

Allows creation, reading, update, deactivation of licenses. All licenses created for customers are based on the root "buyable license" and contain additional owner-specific info.

App created for my fictional man (employee) that manages my (fictional) company's database. Has both CLI, Web and obviously SQL interface.
