I will develop embedded iot firmware esp32 stm32 nrf52 raspberry pi ble mqtt lora rtos

I design and develop embedded systems from concept to completion, 

covering firmware development, hardware integration, and product testing.

I specialize in IoT firmware across ESP32, STM32, nRF52, and 

Raspberry Pi, with experience in BLE, LoRa, MQTT, RTOS, HMI 

displays, and IoT security.

What I Deliver

- Firmware in Embedded C, C++, and Python

- IoT firmware for WiFi, Bluetooth, BLE, and LoRa

- Edge AI and on-device intelligence integration

- HMI display development using LVGL library

- Touchscreen and GUI interface design

- Sensor integration and data acquisition

- Hardware protocols: UART, SPI, I2C, and CAN

- FreeRTOS and Zephyr RTOS integration

- Hardware debugging, testing, and optimization

- PCB schematic design and layout

- Cloud connectivity via MQTT, HTTP, and HTTPS

Platforms and Tools

- Microcontrollers: ESP32, STM32, nRF52, Raspberry Pi

- Display and GUI: LVGL, TFT displays, Touchscreen

- Protocols: UART, SPI, I2C, CAN, MQTT, HTTP, LoRa

- Languages: Embedded C, C++, Python

Note: Please contact me before placing an order. Embedded systems 

and IoT firmware projects require clear scope and technical 

alignment before work begins.
