Best/Worst dev experience 2017:

Well I started my DevRant-Stats site and got my RandomQuote bot up and running again (although the quotes aren't as good as before)

I also started a little company with my friend and made some sites for clients.

I reached #13 on Sololearn in Austria! Kinda proud of it.

I learned Lua and Ruby which are one my favorite languages now!

And as always I started some side projects that I've never finished...

Don't remember everything I experienced in 2017 but these are some I won't forget.
