In the summer of 2021, I had the opportunity to do an internship at https://sascha-nos.com, where I was asked to develop a website where users can add and manage their subscriptions. I also implemented a notification system that informs users in real time about the latest updates to their subscriptions. Unfortunately, the source code is private and the site was occasionally unavailable at the time. Therefore, I show some pictures of the website from my internship report here.
