ESP32/Arduino Firmware & IoT Prototyping Built for Real Deployment


I'm an embedded/IoT engineer with 5+ years building firmware that runs unattended in the field not demo code. My work is deployed at 100+ telecom sites across Pakistan.


WHAT I BUILD

ESP32/ESP8266/Arduino firmware Arduino, ESP-IDF, Raspberry pi, or Zephyr RTOS, stm32

Wireless: WiFi, BLE, ESP-NOW, LoRa

Industrial protocols: Modbus RTU/RS-485, MQTT, SNMP

Sensors: DS18B20, DHT11/22, accelerometers, I2C/SPI

Web dashboards

PCB review, board bring-up, debugging

Bug fixes on existing firmware


REAL PROJECTS

- Industrial monitoring platform (ESP32+RS-485+wireless mesh), 100+ telecom sites

- ESP-NOW smart lock system with mobile app control

- Zephyr RTOS drivers for energy monitors & LoRa radios

- Modbus RTU dashboards for field technicians

-Arduino DIY projects

-PCB Design for rapid prototyping


WHY ME

Most freelance firmware breaks outside the demo. I build for edge cases power loss, sensor dropout, interference because that's what real deployment demands.
