I spent a lot of this summer working on an app for my local 4-H Fair. I worked on a system that allowed the fair people to send notifications/important message to visitors and volunteers, as well as an app that had lots of necessary information.
github.com/caburum/sc4hfair-notification-sender has the code for the interface to send notifications
github.com/cyfinfaza/sc4hfair-sveltekit has the main app code
github.com/cyfinfaza/sc4hfair-webpush has the server that manages sending out the webpush notifications to all the subscribers
for both learning about how the minecraft bedrock api works, and wanting to better track playtime than available in the build in realms timeline, i wrote a plotly/dash python app that displays playtime data in a viewable format any realm
one main pain point was trying to make the x-axis scale nicely to not have too much information when zoomed out, but still show the hourly data when zoomed in to a specific day

made a quick little tool to remotely sleep/wake my main desktop since i don't want to leave it running constantly, but still need to sometimes access it, before i go on vacation
