Über diesen Service
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.
Send your requirements, even rough ones. I'll ask the right questions before you order.
