Thoughts on the design?

Hey this is the first time i post here.

I just started working part-time for this company last week. What i have to do is to change some windows from Win32 to WPF. As i was reading the legacy code i just had to sigh man. They have like 100 projects in a single solution, from C++ to C#, everything acctached to each other, with almost NO comments or docs. Wtf man? I don't know how it actually works in the industry (this is my first dev job) but when you write fucking 20 classes with each one contains bunch of attributes, methods, properties, you can't just leave all the code's semantics in their names. And by the way the app is so fucking ugly i bet they have appointed part-time developers as UX engineers... Even i have little knowledge about UX/UI, i just can't bear with this kind of ugly and confusing and unintuitive production with a cost of a good photo editting software.

Ok there may be much more to rant in the future but let me try through this and tell you more. Have a good day. :)
