Built a real-time fish measurement and feed tracking system for aquaculture, deployed on NVIDIA Jetson AGX Orin with OAK-D stereo cameras. Worked remotely with the client on stereo camera calibration, depth-based fish length/height estimation, and parallel feed pellet tracking, plus a custom PyQt5 app for live monitoring and control. Solved key challenges in real-time performance, GPU memory optimization, and camera calibration on constrained edge hardware all through remote hardware collaboration.
