Emre O.

I am ElectronicalDoctor, an electronics and embedded systems specialist who brings circuits back to life. I diagnose, repair and redesign electronic hardware, develop firmware for STM32/ESP32, build IoT devices, and design 3D printable mechanical parts for drones, robots and prototypes. What I do best: • Circuit diagram and PCB design • PCB repair, fault diagnosis & reverse engineering • STM32 / ESP32 firmware development (HAL/LL/IDF) • IoT systems using LoRa, WiFi and BLE • Sensor integration, data acquisition & motor control • Raspberry Pi automation and Python tools • RF experience including antenna tuning (HF/VHF/UHF), baluns & matching networks • 3D CAD modeling for custom drone/RC/robotic parts • End-to-end prototyping: hardware + firmware + mechanical design Whether you need a PCB repaired, a prototype built, firmware developed, or a long-range IoT solution designed, I deliver reliable, engineering-grade results with clear communication and fast turnaround. Let’s bring your project to life.
