Summary

I have professional understanding of microcontrollers and writing software for them. I have concentrated on developing firmware and kernel modules, but when there is a need I learn fast and quickly jump into middle or application layer to provide a complete framework and diagnostic tools. I am an avid achiever and take pride of my work. I am never afraid to roll up my sleeves and investigate unstructured issues, so that I can properly design SW to deal with them.
