About
I'm an IoT hardware and embedded systems engineer with 8+ years of experience
taking connected products from concept to mass production. I design
production-ready PCBs (Altium Designer, KiCad) and write embedded firmware for
ESP32 / ESP32-S3 / STM32 (FreeRTOS, ESP-IDF, Arduino, MicroPython). On the cloud
side I build MQTT/OTA device backends (AWS IoT, ThingBoot cloud platform) with
device shadow and remote control.
What I've built:
- Founded Xinbu (Chengdu) Technology and lead the ThingBoot open AIoT ecosystem
(ESP32/STM32 SDKs plus an IoT cloud platform).
- Created NewBeeMaker, an ESP32 MicroPython IDE with local simulation and
one-click OTA deployment.
- Designed and shipped an IoT audio product line (6,000+ units via OEM/white-label).
- Built SuperScreen, a B2B digital-signage platform.
I can help with schematic and PCB design, BOM, firmware (Wi-Fi, Bluetooth, MQTT,
OTA), sensor integration, low-power design, and IoT cloud connectivity. I deliver
clean, documented, production-ready work.
