About this Gig
Hey there,
I specialize in ESP32 firmware development using Embedded C/C++ and FreeRTOS, with deep sleep optimization for battery-powered IoT trackers. GNSS integration includes u-blox NEO-6M, NEO-M8N, and Quectel L76K for accurate positioning.
For connectivity, I implement GSM/GPRS, LTE Cat M, NB-IoT, and LoRa solutions using SIM800L, Quectel BG95, and SIM7070G modules. MQTT tracking systems and OTA firmware updates are supported for seamless cloud integration.
What You Will Get
- Optimized ESP32 firmware (Embedded C/C++ / FreeRTOS)
- Accurate GNSS integration (u-blox}
- LTE-M / NB-IoT / GSM or LoRa connectivity setup
- MQTT cloud-connected tracking system
- Deep sleep optimization for long battery life
- Reliable Li-ion battery management design
- Manufacturing-ready schematic and PCB files
- CE/FCC-ready hardware design practices
- Clear documentation and source files
Why Choose Me
- End-to-end hardware and firmware development
- Real-world GPS tracking and fleet management expertise
- Focus on stability, efficiency, and scalability
- Clean, modular, and production-ready design approach
You will receive optimized firmware, production-ready hardware design, and complete documentation for deployment.
