DataGrid: AI-Powered Analytics Platform
Challenge
Non-technical users can't query data without SQL.
Solution
Production-deployed analytics platform with a natural-language-to-SQL pipeline, sandboxed query execution, real-time SSE streaming, and auto-generated Recharts visualizations. Includes a Gaussian Copula synthetic-data engine with fidelity metrics and a text-to-SQL eval harness with execution-accuracy benchmarking tracked in MLflow.
Key decisions
Two-model Claude Sonnet/Haiku split for cost/latency; DuckDB for in-process analytical queries; execution-accuracy eval harness over exact-match.
