POKEPRICE
End-to-end Pokémon card identification and live pricing mobile platform paired with an ML backend.
- Architected React Native (Expo) mobile client with FastAPI backend using OpenCV perspective correction, ConvNeXt V2 classification, & EasyOCR for 100+ card classes.
- Trained ConvNeXt V2 classifier in PyTorch on 20,000+ labeled card images (~90% recognition accuracy).
- Tuned EasyOCR with character allowlisting for fast CPU text extraction; optimized image preprocessing with Expo Image Manipulator (cut payload size ~60%, API speed ~40%).
- Designed RESTful API delivering card identification & live pricing in <2s average; cached scan history using Redux Toolkit & AsyncStorage (~50% API call reduction).
