The thesis describes the creation of a system that will optimize and facilitate the communication and workflow for a company engaged in picking up and delivering express shipments. We will present the client's requirements through user stories and acceptance tests. We will introduce a Docker tool, which allows developers to reduce the time needed to build and deploy the system. We will present Docker's use for building, distribution and deployment of various components that are necessary for the system. We will present user interfaces used by employees to interact with our system. The result of this thesis will be a functioning system that facilitates communication about new delivery orders between dispatchers and couriers. In addition to optimized communication, the system will allow for a complete overview of orders, dispatchers, couriers, and mobile devices.
