Real-time Computer Vision & Edge AI engineer with a deep C/C++ systems and embedded background. I build AI that runs live on real hardware - not just in notebooks. My focus is real-time video analytics on the edge: object detection, tracking, recognition, and TensorRT/CUDA optimization deployed on devices like NVIDIA Jetson. A strong C/C++, embedded, and Linux systems foundation means I care about the whole system - latency, memory movement, post-processing, UI smoothness, deployment, and failure cases - not just model accuracy. I also build LLM-powered applications that connect models to tools, documents, APIs, and business workflows (RAG, tool calling, automation). Recent work - VisionGuard AI: real-time retail shelf recognition on Jetson Orin NX - Live RTSP video analytics on edge hardware - Dense product detection with GPU-side post-processing - Stable object tracking across frames - Embedding-based SKU recognition - Unknown-product rejection instead of forced labels - Runtime recognition updates without restarting the camera stream - Smooth UI overlay under dense shelf conditions I can help with: - Real-time computer vision systems - YOLO / custom detection pipelines - TensorRT, CUDA, Jetson optimization - Multi-camera RTSP video analytics - Edge AI deployment and debugging - LLM apps with RAG, tool calling, and workflow automation - Python/C++ AI backend integration Core stack: C++ - Python - Qt6 - TensorRT - CUDA - YOLO - OpenCV - RTSP - NVIDIA Jetson - Linux
