Almuerza.co s a web app designed for small restaurants. The purpose is to give a dynamic menu and a portal where they can receive orders inside or outside the restaurants. Each restaurant has its own clients database. The clients also have authentication to handle the status of the orders. This system involves development in frontend using HTML, CSS, Javascript, Jquery. The authentication method was using firebase. The orders and some users' information using SQL. I also design a thermal printer that prints the order in the kitchen it works with firebase cloud functions and MQTT protocol.
