InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
There's Learn Haskell by building a blog generator and Applied Functional Programming Course for web project courses. But I think the latter is outdated.
For theoretical, maybe Category Theory for Programmers. I don't own the book, but I've seen it mentioned a few times.
