It's nice to see your motivation!
Offline would be good if you can, of course. If not with someone you know, maybe you can at least ask some questions at a local coding meetup?
There is a website codementor.io that may be useful, but from what I've seen it's really expensive.
Here might be a good place too. Maybe wouldn't actually be a bad idea for Hashnode to facilitate that somehow (similar to what italki does for language partners).
