Love programming for various aspects:

• solving problems
• building large systems that magically work on their own
• build frameworks that others can build upon
• structure logic and ideas in an elegant and fluent way

Using Java at work, Scala at home, and wish I could learn more about Clojure. I'm also looking into Kotlin a little bit although I don't want to cheat on Scala, but I reckon it would be easier to introduce Kotlin in my work than Scala!
