An NL2SQL system that lets non-technical users query a sales database in plain English and get accurate SQL back — no schema knowledge required. Built a custom synthetic dataset of 1000+ NL-SQL pairs across simple, medium, and hard complexity tiers on a realistic e-commerce schema. Fine-tuned Llama 3.2 1B on this dataset and deployed the model to HuggingFace Hub with a live Gradio demo — end-to-end from data generation to public deployment.
