It's not clear how you meant that but the reply you received interpreted it as a swipe (and it landed that way with me as well), so I've detached this subthread from https://news.ycombinator.com/item?id=38493152.
Yeah should have articulated better, could sound snarky like this.
Meant to ask if such a long list of skills is genuine for 2 years of experience; not to make him feel bad, but that's what people hiring will also think.
It might be that he's exceptionally smart, or that he did much more then the 3 projects described, but would be good to justify and/or specifiy skillevel per langauge better.
