I have an experience of almost 20 years in C++ (especially in RT systems). I also did some iOS and Android backend. I was a C++ Infrastructure Team Leader, Algorithms Team Leader and an architect. I'm a lecturer in Bar-Ilan University and Ariel University for advanced programming courses. I wrote the syllabus for some of the main programming courses in the CS department, Computer Engineering, Computational Biology and Brain Studies departments in Bar-Ilan University. My Ph.D. subject was on improving compressing algorithms to enable searches without uncompress the files.
