Image-to-Image Visual Search

Let me walk you through how I'd design an image-to-image visual search system at production scale. I'll go stage by stage – business and ML objectives, high-level design, data and feature strategy, embeddings, pipeline architecture including modeling and training details, infrastructure, evaluation, and robustness. This system lets users search using images rather than text queries, finding visually similar items, products, or content across billions of images.
