AI agent - Talk to my database

We're looking for an experienced AI/backend developer to build Zelda, an internal AI assistant that can communicate directly with our databases using natural language. The goal is to allow our team to ask questions such as "How many drivers went online today?", "How many trips were completed this week?", "Which city had the highest demand yesterday?", or "Show me all drivers who haven't completed a trip in the last 30 days." Zelda should understand these requests, securely query our databases, and return accurate answers in plain English, tables or charts. It should also be able to perform authorised actions, such as updating records, creating data, or generating reports, while respecting role-based permissions. The ideal developer should have experience with Node.js, MongoDB, SQL/NoSQL databases, AI integrations (OpenAI or similar), natural language processing, and secure backend development. Experience building AI agents, database assistants, analytics dashboards or business intelligence tools is highly desirable. Please include examples of similar projects and explain how you would build a secure, scalable AI assistant that can safely interact with production data. Response can be sent to our dashboard screen where we already have HTML templates for
