I have 20+ years of experience as a professional software developer. One of the main tasks in my career was and is the implementation of communication protocols via various physical interfaces like RS232, USB and Ethernet. I mostly program C++ and C but also gained experience in C# and Python. I developed on various platforms like Windows, embedded LINUX and Nucleus RTOS. I have a lot of experience in cryptography, multithreading, object orientation and embedded programming. In my free time, I deal with computer graphics and have experience with OpenGL and the Vulkan Graphics API.I have a quick grasp, I am motivated and work independently and customer-oriented.Currently I am in a permanent position.
