I have a Bachelor Degree in Computer Science and Mathematics from the University of Toronto. I am a c++ developer for realtime systems previously working at Huawei Technologies. I mainly enjoy working on systems that get very complicated, and require infrastructure to determine if the system is running properly, to me a system that doesn't crash doesn't mean its a system that is running properly. I have good knowledge of how to architect systems that will become very complicated and make it scale. I have created a game engine in c++ using my a technique which allows me to compose a bunch of smaller projects/code into a entire program. This methodology allows me to isolate the parts that's not working correctly and perfect it, then re-import it, and so far there hasn't been a bug that I haven't been able to handle.
