- React
- Clojure (for the backend)
- Firebase (Great for quick web prototypes and large web scale apps)
- Cassandra (but will I ever host my own cluster again?)
- JVM
- Cloudformation (Yes, the syntax is annoying, but it's nice being able to delete an entire formation of AWS services off in one hit)
(I have had minimal or no experience with these - they sound like a cool idea)
