At ShareXtent, I architect and implement real-time multi-camera imaging pipelines on NVIDIA Jetson AGX/Orin, combining C/C++, CUDA, GStreamer/DeepStream, OpenGL ES, EGL, AI, and display systems.

I bring up and debug IMX camera systems across CSI-2 and GMSL, modify drivers and sensor modes, tune ISP pipelines, and solve multi-camera synchronization and timing issues. I build GPU-native NVMM, DMA, and CUDA-EGL data paths, custom CUDA transforms, and image-processing stages for distortion correction, denoising, compositing, and AR overlays.

I deploy TensorRT, DeepStream, YOLO, OpenCV, and PyTorch pipelines for detection and segmentation, reducing inference and response latency from about one second to about 100 ms through model, pipeline, and GPU-path optimization.

I also prototype RAG and Llama-family model capabilities, integrate LiDAR, thermal, GPS, and IMU sensors into synchronized graphics systems, and create Blender-based printable enclosures and visualization assets that move R&D concepts toward physical products.
