I like to think of myself as a somewhat all-round player with experiences in many not necessarily related technologies. In my daily job I work mostly with C# as well as database design/management in SQL server. Web development with Angular/JavaScript even some embedded development in C and Python.

Mostly interested in problem solving in general, But if I have to pinpoint it would be: software optimization, architecture, APIs, back-end systems, design patterns, refactoring, TDD, parallel and asynchronous programming concepts, low level programming (as in IoT, embedded systems), and a lot more...
