About Me

AI engineer and photographer based in Taipei, Taiwan.

I'm a Computer Science and Engineering graduate of National Taiwan Ocean University (Class of 2026). RiffNode — a guitar effects studio built entirely with native Apple frameworks — won the Apple WWDC26 Swift Student Challenge.

At ITRI I trained and deployed multi-task driving-perception models down to a Jetson Nano. I led my capstone team's volleyball analysis system, which won the department's Software Development Silver Award, and I have kept building it as a research project — from one camera to the court in metres, tracked players and 3D ball flights. Lately I have been auditing whether guitar-tone models quietly change a player's touch, and building a macOS app whose architecture the compiler enforces. I like working across the stack — on-device ML, audio DSP, systems Swift — and turning hard problems into things people can actually use.

AI Image Recognition Intern

ITRI (Industrial Technology Research Institute)

Electronics and Optoelectronics Research Laboratories

Hsinchu, TaiwanJun. 2025 – Aug. 2025
  • ·Trained YOLOPX, a multi-task panoptic driving perception network doing object detection, drivable-area segmentation and lane segmentation in a single forward pass — reaching 0.972 mIoU (drivable area), 0.793 mIoU (lane) and 0.838 mAP@0.5 over 4 classes after 200 epochs on ITRI's in-house driving dataset
  • ·Extended the open-source YOLOPX codebase by ~1,900 lines (6 files rewritten, 5 added) for ITRI's data format, building a YOLO-segmentation loader and a Mosaic/MixUp/Albumentations augmentation pipeline to replace one that handled BDD100K only
  • ·Owned the edge deployment path: network pruning, ONNX export, a tool resolving dynamic convolution-bias subgraphs that blocked TensorRT conversion, a TensorRT/PyCUDA engine for NVIDIA Jetson Nano, and image + detection streaming to a desktop PC over Ethernet/ROS at 30 FPS with sub-50ms latency
  • ·Delivered a command-line batch-inference tool for ARTC (Automotive Research & Testing Center) running the trained model across image and video datasets including a new rainy-weather set; separately reproduced and benchmarked YOLOP, YOLOPv2, YOLOPX and A-YOLOM to identify deployment-viable designs

Beyond Code

Off the clock I captain my department's volleyball team, play guitar, and develop film as darkroom officer of NTU's photography club. I'm a PADI Open Water diver, paddled the 10 km kayak crossing to Keelung Islet, and spent two days volunteering at the Chengdu Research Base of Giant Panda Breeding. Most of it ends up in front of a camera sooner or later — the results live on the Photography page.
