Microcontroller Programmer, Electronics Engineer

I have over 7 years of professional experience in the development of firmware (on C language) for automation, vending and IoT projects. Below is a summary of some of the technologies I’ve worked with. 1. IAR embedded workbench; 2. STM32/STM8/AVR microcontrollers; 3. RTOS; 4. Multi thread development; 5. Ethernet/WI-FI; 6. BLE; 7. USB; 8. TCP/IP (TCP, UDP, Sockets, REST, HTTP, SNMP, FTP, DNS); 9. Master - Client architecture; 10. JSON; 11. Modbus RTU/Modbus TCP; 12. KNX; 13. RS232/RS485/RS422; 14. UART/SPI/I2C/1WIRE/IR; 15. EEPROM/FLASH memories, LCD/TFT/Segment displays, Sensors and so on. I have basic knowledge of HTML/CSS/Javascript/NodeJs. I can develop responsive web applications and provide communication between web and device. I have a notable experience with ARDUINO, ESP32, and ESP8266. There is a huge set of ARDUINO/ESP32/ESP8266 hardware (sensors, displays, shields, motors) available to me. I will be happy to help translate your ideas into reality.
