Über diesen Service

I specialize in IoT and wearable product development from concept to production.

My experience covers embedded hardware design, firmware development, wireless connectivity, prototype bring-up, validation testing, and manufacturing support.

Completed projects include:

  • BLE and Wi-Fi wearable devices
  • nRF52/nRF53 and ESP32 based IoT products
  • STM32 and EFR32 embedded systems
  • Low-power battery-operated devices
  • Smart sensor and data acquisition systems
  • LTE, GNSS, BLE, Wi-Fi, and sub-GHz wireless products
  • Health monitoring and wearable tracking devices
  • Custom embedded Linux and RTOS-based systems
  • Prototype development and production-ready hardware

Technical expertise includes:

  • Firmware development using C/C++
  • FreeRTOS, Zephyr, ESP-IDF, STM32CubeIDE, nRF Connect SDK, and Simplicity Studio
  • PCB design with Altium Designer, KiCad, and EasyEDA
  • Hardware bring-up, debugging, validation, and optimization
  • Communication interfaces including BLE, UART, SPI, I2C, CAN, USB, and TCP/IP
  • Low-power optimization and reliability engineering

I focus on building reliable, manufacturable, and production-ready IoT solutions with clear communication and efficient development workflow from idea to final product.
