What I'm looking for

I'm looking for global remote Embedded Linux, IoT, edge gateway, Linux platform, or BSP roles where I can independently own products, solve complex system issues, and contribute across firmware, networking, OTA, production, and customer-facing delivery.

I currently own nearly the entire software stack for industrial BLE and LoRa gateway products at Shenzhen Huachuang Hengda Technology, from MTK7688 and OpenWrt platform migration through device integration, networking, MQTT, OTA, production tooling, and customer-site debugging.

Previously, I built Linux industrial data-acquisition gateways at Dongtu Technology and led core development for industrial control firewalls at Beijing Tiandi Hexing. My work includes Suricata-based DPI, Modbus/S7/OPC protection, DDoS defense, routing, OpenVPN, IPsec, and Python-based device-management services.

Across 14 years, I've delivered embedded Linux routers, smart-home gateways, industrial gateways, and security products using OpenWrt, Buildroot, U-Boot, C/C++, Python, and Linux networking. I enjoy independently owning complex products from flash layout and bootloaders to firmware delivery, field deployment, and system-level troubleshooting.
