At 4DAGE Technology, I solely own the Android and Flutter codebases for 4D Kankan / Eight-Eye, a production 3D spatial-scanning app with roughly 110K lines of code. I build the mobile stack from capture and reconstruction through release, combining real-time SLAM, point-cloud rendering, multi-camera hardware, and Flutter-native integration.

I’ve designed bridges exposing 40+ native capabilities to Flutter, integrated SFM, OpenCV, TensorFlow Lite, LiDAR calibration, Three.js/WebGL rendering, and NDK C++ point-cloud conversion. I also build GPU multimedia pipelines with OpenGL ES, FFmpeg, ExoPlayer, and RTSP, while tuning adaptive rendering, memory, threads, and long-running capture reliability.

Earlier, I developed smart-sensor algorithms, cross-platform BLE SDKs, Android framework applications, tourism products, and Spring Boot services. I’m looking to help a global team build ambitious mobile products remotely.
