HELLO AND WELCOME

Reliable embedded firmware is essential for responsive USB and Bluetooth devices. Poor protocol implementation, unstable communication, inefficient firmware architecture, and hardware integration issues can delay development and impact product performance.

I develop professional embedded firmware for STM32, ESP32, RP2040, nRF52, and other ARM-based microcontrollers, delivering stable USB HID, Bluetooth HID, BLE, and custom communication solutions for commercial products and prototypes.


Services Include

  • USB HID firmware development
  • Bluetooth HID & BLE firmware
  • STM32, ESP32, RP2040 & nRF52 programming
  • Embedded C / C++
  • FreeRTOS integration
  • USB-C communication
  • UART, SPI, I2C & CAN protocols
  • Bootloader implementation
  • Low-power optimization
  • Sensor and peripheral integration
  • Firmware debugging & optimization
  • Hardware bring-up and validation

Deliverables

  1. Complete source code
  2. Project files
  3. Firmware documentation
  4. Communication protocol implementation
  5. Build configuration
  6. Technical support

Whether you're developing a USB device, Bluetooth product, custom controller, industrial equipment, or IoT system, I deliver robust embedded firmware engineered for reliability, maintainab
