Hey I'm Jo. I have a master's degree in computer science and love building web applications. Currently I mainly use TypeScript, React and PHP.
Built a React component to show activity data in a heat map (like GitHub does for contribution data).
Built a Progressive Web App called Daddel (from German dad·deln, meaning to play) to organize game nights with your friends. Daddel solves the problem of finding a date with a large number of people: Users can create lobbies for a specific date and game, others can then join them. By specifying the time period in which each person is available, a useful calendar can be created. Think of it as Doodle for game nights.
