Most AI apps stop at “upload → ask → answer”.I’m building Cortex to go deeper — as a scalable data processing + retrieval system.Here’s what’s happening under the hood : Users upload documents → stored via pre-signed URLs (S3) → metadata persisted → async processing kicked off via a queue (BullMQ).A worker pipeline then: • Downloads &amp; buffers the file • Extracts text (PDF parsing) • Chunks the data • Generates embeddings • Stores everything in a vector databaseOn the query side: User question → embedding → similarity search → context retrieval → LLM responseAll of this is stitched together with: • Async job processing (BullMQ) • Real-time updates via SSE • Modular services sharing a common data layerCurrently in Phase 1, focusing on getting the ingestion + processing pipeline rock solid.The goal is to evolve this into a production-grade knowledge engine, not just another chatbot.Would genuinely love feedback to improve on the current implementation.
