I have an experience of 10year+ as a sys admin (windows/linux/cisco). Because programming is what I like to do best, and do it well, for the last 3years I do devOPs.
I do .NET programming for desktop and mobile, web programming, low level programming, hardware-software interfacing and hardware prototyping. I do electronic design for almost 10 years: I can do everything from designing circuits, develop and program microcontrollers, design PCBs and appliance housings. I have designed several projects using (but not limited to) the following technologies: 802.11b/g/n WiFi, Bluetooth, LIN Bus, CAN Bus, USART and other serial protocols based on it, I2C, SPI, various types of LCDs, motor control, thermal control, DSP, GPS.
