I'm building a sports analytics platform, where users can write code against a hosted sports database, add commentary, and publish to build a sports data science portfolio. All published articles include the code, and any reader can fork someone else's work to do their own work building off others.
If anyone wants to learn sports analytics, I'm looking for beta users. (Also open to adding non-sports datasets if someone wants a hosted dataset with built in publishing for e.g. SEC filings, crypto prices, etc.)
