Enterprise Data Querying with Local LLMs

The Challenge: The client needed to extract insights from sensitive corporate data using natural language, but moving this data to a public cloud was a strict compliance risk.

The Solution: I architected and delivered a completely local, privacy-first AI environment. By engineering lightning-fast local data pipelines, the system analyzes raw data files directly from disk in sub-seconds. Paired with a localized Generative AI model and a rapid UI, the client can now securely "chat" with their data.
