    "We choose to go to the Moon [...] and do the other things, not because they are easy, but because they are hard" JFK I learn fast and have strong math, analysis and problem solving skills. I'm quite durable when facing a frustrating problems. Fixed and maintained projects written by others many times as well as built the working solutions from scratch myself. Daily Linux user. Can natively work on Mac or Windows as well. As a teenager I passionately coded games, map editors and simple utils in C++ and Python, but studying sound engineering and acoustics at the University got me really hooked into the highier math concepts, numerical computing and DSP in general. It introduced me to the Matlab/Octave as well. I quickly realized I can solve many practical real-life problems with my existing programming skills and all the new knowledge catalyzed my further development as a programmer greatly. During the following 20 years I worked on various projects and am constantly improving my skills and experience. Audio, DSP and physics-related utilities are not my only areas of expertize. I still like programming for video, graphics and games in mind, embedded hardware and more general computing as well. I love innovating and constantly work on my own inventions. Always open to learn new things and to make the world a better place. Let's do it together!
