An AI platform that turns plain-English questions into SQL. It connects to MySQL or PostgreSQL at runtime, reads the live schema, and sends the schema and question to a fine-tuned Qwen 2.5 3B LoRA model trained on Google Colab. Generated queries are validated as read-only (SELECT/WITH) before running, and results are returned as JSON through a FastAPI service packaged with Docker.
