More than 20 years of professional experience, expertise in Linux, C/C++, Python, Erlang, advanced algorithms, system analysis. Open to various offers, but mostly interested in Linux kernel, currently. Fixing bugs, solving complicated problems, creating / reshaping systems. The result is most important of all things. There are no borders between various disciplines of programming. A high power output, not for every appliance. :) Getting things done.

I have developed a wide range of desktop products, using C, C++, STL, Win32, Visual C++, MFC, COM, QT and C#, and Office Addin development. During my work in five Product Engineering teams, I have also created functional requirements, defining the scope of work , proof of concept, software design, software development, and client interfacing. Besides being an Individual Contributor, I have also played Techno Managerial roles - requirement gathering, software design, work breakdown, and end to end implementation of projects within the scheduled time . I also have experience on UML, Software Architecture and creating software roadmaps.
