XRCC Hackathon β Louvre XR Backend π 2nd Place, WebXR (Meta IWSDK) Track
FastAPI backend for a museum XR companion: GPT-4o Vision exhibit recognition, FAISS RAG, navigation lookup tables, multi-turn conversation β deployed on Railway. Built the case for deterministic lookup over GenAI where determinism wins (exhibit ID matching, 56-route navigation).
Also shipped a same-weekend Android app integrating Ray-Ban Meta AI Glasses via the Meta Wearables DAT SDK, after discovering WebXR lacks camera/mic access on that platform.

A Deep Learning Framework of Super Resolution for License Plate Recognition in Surveillance Systems
Built a real (not synthetically degraded) dashcam dataset; designed two novel perceptual losses (Swin Transformerβ and CRNN-based) so the model optimizes for downstream OCR accuracy, not just pixel-level image quality.
+10pp OCR accuracy improvement over baseline
