I haven't used couchsurfing much but am no stranger to hosting strangers at my place - excuse the play on words. I left Germany when I was 18 and haven't lived there ever since. I lived two years in Australia, six in the UK and now going onto six years in Thailand. I like learning new languages but work as a programmer with Unreal Engine. As I am currently traveling around a lot I am not able to host people but in case you come by Bangkok after September 2019 I gladly host you in return!
