My bachelor project resulted in the architecture currently used by Frontsafe's SMARTtsm product.
I take pride in my code. Code needs to be consistent and easy to read. I recommend you read the book Clean Code by Robert C. Martin if you also take pride in yours!
I loved Qt from the first time I prototyped an application with it. Qt is also a full replacement for the std C++ library, making it useful for console apps as well as UIs.
I have loads of experience programming for AIX and GNU/Linux.
