Is your Arduino or ESP32 project stuck compiling but not working, or not compiling at all?

I debug Arduino and ESP32 code, whether it's a simple sketch throwing errors or a complex multi-sensor system behaving unpredictably. I find the root cause, fix it cleanly, and send back well-commented code you can actually build on.


What I work with:

  • Boards: Arduino (Uno, Nano, Mega, Pro Mini) and ESP32 / ESP8266
  • Sensors & Modules: DHT11/22, MPU6050, OLED, LCD, relay, servo, motor drivers, and more
  • Communication: I2C, SPI, UART, Wi-Fi, Bluetooth, MQTT
  • Other: Library conflicts, memory issues, timing bugs, interrupt problems


Why choose me:

  • I don't just patch the symptom I fix the actual problem
  • You get your code back clean, commented, and easy to extend
  • I explain what went wrong so you can avoid the same issue next time
  • Fast turnaround most debug jobs completed within 24 hours


I've worked with motor control, cloud-connected IoT systems, RTOS multitasking, and Firebase integrations so I've seen most failure modes before.

Not sure if your issue is fixable? Message me with a quick description and I'll give you an honest answer before you order.
