I will design esp32 stm32 with gps lora iot ble for embedded pcb design custom firmware

Need a reliable engineer to develop a complete LoRaWAN embedded system, custom PCB Design, and production ready firmware? I design ESP32, STM32, nRF, Raspberry Pi, GPS, BLE, LoRa, and LoRaWAN embedded systems with professional hardware, firmware, and IoT integration.

I specialize in LoRaWAN embedded systems, custom PCB firmware hardware, and ESP32 STM32 GPS LoRa IoT BLE solutions for tracking, sensing, industrial monitoring, and smart devices. Using Altium Designer and KiCad, I develop multilayer PCBs with controlled impedance routing, signal integrity, power integrity, and RF aware layouts. My firmware expertise includes ESP-IDF, STM32CubeIDE, Arduino Framework, FreeRTOS, Nordic SDK, and Raspberry Pi Linux environments.
