About this Gig
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.

FAQ
Do you provide the hardware?
No, I work with schematics/code; I can recommend parts but don't ship hardware.
Can you fix my existing code?
Yes, send it over and I'll review before you order.
Do you sign NDAs?
Yes, happy to for Standard/Premium orders.
What do i need to get started with the project?
a list of requirements from your end before the order is placed so i can guide you accordingly.
