Have an idea but don't know how to code it?


I'll write clean, fully working Arduino or ESP32 firmware tailored to your exact project from a simple sensor read to a full IoT system connected to the cloud.

No copy-pasted examples. No messy code. Just well-structured, commented firmware that does exactly what you need.


What I can build:

  • Sensor & display projects DHT, MPU6050, OLED, LCD, and more
  • Motor, servo & relay control systems
  • Wi-Fi and Bluetooth projects (ESP32)
  • Cloud connectivity via MQTT, Firebase, or HTTP
  • RTOS and multitasking firmware for complex builds
  • OTA update systems for ESP32


What you get:

  • Clean, readable, well-commented source code
  • Logic that's been thought through not just stitched together
  • Circuit & wiring diagram (Premium only)
  • A coder who explains what they built and why


Not sure which package fits? Message me before ordering. Let me know what you want to build and I'll point you to the right tier no pressure.
