Built a Content-Based Image Retrieval (CBIR) engine extracting 2048-dimensional CNN feature embeddings from ResNet50 into partitioned FAISS vector indices for efficient similarity search., Optimized vector indexing and cosine similarity (inner-product) computations to deliver sub-100ms query latency across large image catalog databases., Packaged and deployed an end-to-end FastAPI microservice with interactive web UI, Docker support, and live hosting on Hugging Face Spaces for public access.
