*SUMMARY An Earth's physicist by education, I work as software Engineer over 30+ year with experience ranging from main computer frames to modern Windows / Linux PCs and embedded devices. I always considered programming as a tool to reach my scientific goals and not as profession by itself. My primary interests are Inverse Tasks, Linear Algebra, Navigation, Remote Sensing, GIS and map production applications. I also have passion for Linux, from desktops to embedded systems. During my career I developed complete complex multi-threaded UI solutions from top to bottom, including algorithms, data handling and processing, presentation and documentation. My primary language is C++11, but I also have experience with Python, PHP, shell scripts and other tools. My Open Source Community contributions are in C/C++ and Python.
