Firmware programmer, PCB designer, robotics engineer

I'm a programmer, PCB designer and scientist in our Ultimate Robotics team (we develop prototypes in wearables, sensors and robotics). I specialize in PCB design, writing firmware and creating custom optimized algorithms. Microcontroller programming: — nRF52x, ESP32, STM32Fx/Lx/Gx, Atmega328P/Arduino, ATtiny. Implemented BLE protocol from core specification in order to remove dependency on Nordic softdevice. Wrote drivers for multiple devices (ADCs, IMUs, RF chips and others). Mathematics and algorithms: — IMU processing - quaternion based position integration, fusion of several data sources, analysis of sensor mesh — signal processing, FFT for microcontrollers/SoC/PC with realtime graphical display output — PID control, vector BLDC control — Computer Vision algorithms, especially highly optimized to run on systems with low computational capabilities — Machine Learning, especially neural networks - wrote several papers on new methods in the field, published in high quality peer reviewed journals PCB design/Gerbers for 2/4 layers boards (usually takes from 2 hours to 2-3 days): — sensitive, low noise analog front ends — onboard signal processing (it's best to filter realtime raw data) — single or multiple processors (why not, even Arduino has two) — wireless and RF: BLE, RFID, WiFi and custom RF links — LED matrices, screens, touch/proximity/ordinary buttons C programming on Linux: Often you can't fully utilize hardware system without a PC interface, and Linux with C program is the most efficient choice in this case.
