Jian H.

With over 8 years of hands-on experience in embedded systems and Android development, I specialize in delivering robust, scalable, and high-performance solutions for custom devices, including Set-Top Boxes (STB), Smart TVs, and digital signage. My expertise spans the full stack—from bootloader integration to custom UI development—ensuring seamless hardware-software integration and an optimal user experience. What I Can Do: - Design, develop, and deploy computer vision systems on edge devices (e.g., Jetson, Raspberry Pi, Orange Pi) for tasks such as object tracking, license-plate recognition, and motion analysis. - Build real-time dashboards that reflect live event data (e.g., sales, alerts), including audio/visual feedback. - Customize AOSP-based boards using SoCs from Rockchip, Allwinner, and Amlogic. - Create and maintain automation workflows (using Zapier, n8n, or custom solutions) to connect systems and trigger actions. - Optimize models and pipelines for latency, power efficiency, and reliability. - Collaborate with hardware engineers and product designers to align system requirements (camera specs, sensors, mounts, etc.). - Ensure quality through testing, monitoring, logging, and robust failure handling. Core Skills & Technologies: - Languages: C, C++, Java, Kotlin, Python, Bash - Vision Frameworks: YOLO, OpenCV, TensorFlow - Edge Deployment: TensorRT, Jetson - Android: Android SDK/NDK, AOSP (Android 9–13), JNI, Gradle - Multimedia: GStreamer, ExoPlayer, MPEG-DASH, RTMP, OpenGL, OpenCL - UI Development: Custom UI, Canvas/Scene, Qt, wxWidgets, WPF, Flutter - Build Systems: CMake, Yocto, Buildroot - Hardware Interfaces: USB, I2C, HDMI, GPIO, RCU, Serial, RFID - System-Level: Bootloader, OTA updates, /dev access, power management (suspend-to-RAM/disk) - Platforms: Android TV, STB (Broadcom, Amlogic), RDK, Linux/Windows cross-platform apps
