Development of electronic equipment from idea to prototype

SPECIALIZATION
Embedded systems design, covering both hardware and firmware, making use of microcontrollers/microprocessors along with additional hardware interfacing consisting of both analog and digital circuits. I’ve got considerable experience in the field of electronics products designing, from concept to completion.
Currently specializing in the development of microcontroller equipment. The main platform is STM32 (There is also practical experience with Microchip and Atmel mcu).
My expertise lies in the field of electronics hardware and firmware, including electronic circuits schematics and PCB layout designing:
Embedded systems hardware and firmware design using microcontroller and microprocessors.
Analog and digital electronic devices. In my projects I widely use modern analog and digital element bases, including radio modules and GSM modules, peripherals, including interfaces - SPI, I2C, UART, RS232 / 485, 1-Wire, USB, etc.

As my project examples:
GPRS-oriented microcontroller platform (STM32),
GSM smart modem for monitoring remote metering devices (SIM900 / SIM800, STM32);
Liquid level and temperature (fuel) control sensor
Implemented tasks for:
designing a measuring unit, ensuring a given level of accuracy, thermal stability and linearity of characteristics,
specialized algorithms for filtering measured values, communication with the host device using the Omnicom protocol have been worked out.
Developed: schematic diagram, design and topology of the printed circuit board, firmware (STM32).
