I spent a weekend building a certificate dashboard right into Calendar.app. The front-end may not be React and the back-end definitely isn't written in Go, but it works really well. I didn't even need to install Redis or another NoSQL database. The CRUD is outstanding and the search support is great, even if its not based on Solr.

I ported my solution to both Google Calendar and whatever that thing is that would be the Microsoft equivalent. Full mobile support, entirely cross-platform. You can even use it on someone else's computer I mean cloud.
