The scope of the thesis is to extend the new unified design for JupyterHub to support critical elements such as system announcements (e.g., cluster reboots and software upgrades), additional sections (such as user surveys), add a seamless connection to the backend service and apply the developed solution across all JupyterHub instances within e-INFRA CZ. The student will familiarize himself with the JupyterHub stack, the basics of the web development, creation of container images and deployment of the service in Kubernetes cluster. A key part of the thesis is to  develop the solution in reusable manner to ensure flexibility for future needs and document the process of extending and applying the design, with guidelines for future adaptation to additional JupyterHub instances that may have varying requirements. The output of the thesis is a functional implementation of a new JupyterHub design applied across all existing instances and text of the thesis serving as the documentation.
