I start with that I feel similar type loneliness in my project. I always got a solution that other people were positively surprised of, I'm the problem solver in my small project team, and I also am able to write bulletproof-ish code. And I have exact same feeling, that I don't have anyone around that could, or want to challenge me. I've recently been chatting with my friend, he works for another company, he has the same issue of being not able to discuss solutions with anyone.

I always wished there was a way or a place that people with this 'problem' can meet, chat and ideally brainstorm ideas in their projects or on some other project that they would contribute in.
