Personally I haven’t replied because I don’t feel qualified for the job. I know quite a bit about Godot, a decent amount about databases, can compile for iOS and Linux, and have enough C++ knowledge to get by. The reason I don’t feel qualified for the job is because I haven’t really used C++ and Godot together, so I’m not really familiar with Godot’s C++ API and while I know a decent amount of C++, it’s been awhile since I used it heavily.
As far as I know, and this is just my assumption based on what I have seen, there are not many Godot C++ developers here on the forums, which might explain the lack of replies. That said, it might just be the right person/people haven’t seen it yet.
You might want to also post on Reddit, Facebook, Discord, and/or the Godot LinkedIn group if you have not already. Last I knew there is some Godot C++ developers on Reddit and Facebook, so you might have more luck finding candidates there.
