Ask HN: What service do you use for personal code reviews?

I found that one way to get more acquainted with a new language/stack is to get code reviews by someone more experienced.

Being new to Go/Typescript and looking for personal code reviews on my side projects.

Pullrequest.com seems a bit much for my use case but I haven't tried Codementor.io. Finding specific tasks I want to improve through open source is hard to do at the moment (could be a useful service to build)

What does the HN community use?
