I am a skilled C++ developer with 20 years of experience in different fields from low level to frameworks like Qt and MFC. I also have some experience with Atmel microcontrollers and ARM SBCs. I have high attention to details and code quality (clarity, maintainability, reliability, performance), good problem solving skills, and able to learn new things fast. I have rather good general understanding of physics, math, engineering and technology. Also I have a 3D-printer and printing experience, and some experience in creating simple models in OpenSCAD. For the past couple of years I have been using Linux as the primary OS at home.
