Hi all! It’s great to be part of this community since the very beginning of Voxes.
My name is Patrick and I’m engineer from Poland. I’m working on software that could help you manage users feedback and share product development (https://voxes.io). Of course it has MongoDB under the hood! 
We’ve just launched - if you are developing any project, feel invited to try Voxes
Welcome to the community Patryk! It looks like an interesting product you guys are building!
