We seek a consultant (solo or small team) to take an existing FastAPI prototype that connects an LLM model to a large socio-economic database and deliver a minimum viable product (MVP) for web and mobile use. The MVP must answer natural-language questions from sales staff, selected clients, and lay users with clear tables and charts, and it must accurately pass a provided test set of quantitative questions. We will provide access to the current FastAPI codebase (if required) via GitHub and development credentials for a cloud-hosted SQL Server instance, along with schema documentation and the evaluation test set.
