I’m backend developer, at work, I do kotlin spring stuff

spring boot?  how are you feeling about the spring/Kotlin integration?

Yes, Spring boot. I like it, it makes code much concise, and I start to appreciate more functional oriented 
programming approach. Oh extension function is amazing!

extensions definitely go a long way to make klunky java apis more usable from kotlin.

Yeah, we have a mix of Kotlin and Java usage, more and more ppl adopt Kotlin and finding it better
