About this Gig

Need a reliable C or C++ developer for your microcontroller project? You're in the right place.

Hi, Im Arthur a Mechatronics Engineer and Embedded Systems developer specializing in C/C++ programming, microcontroller logic, sensor integration, PCB design, and hardware prototyping.

I help people and businesses turn ideas into working embedded systems, from simple Arduino scripts to full custom firmware for AVR, ESP32, ARM boards, and custom PCBs.

What I can build for you:

  • Microcontroller programming (C or C++)
  • Arduino, ESP32, ESP8266, STM32, ATmega, RP2040
  • UART, I2C, SPI, PWM, ADC, Timers, Interrupts
  • Sensor & module integration (IMU, OLED, NeoPixel, motors, etc.)
  • Firmware for custom PCBs
  • State machines, debouncing, real-time logic
  • Hardware troubleshooting and debugging

Why work with me?

  • Mechatronics Engineer (hardware + software integration)
  • Clear communication and easy collaboration
  • I explain everything so you always understand what youre getting
  • Professional documentation and clean code
  • I can support you from idea code hardware test

Lets build your project, your prototype, or your full embedded system with precision and speed.
