Full-Stack Developer for AI Chat Platform

We are seeking a skilled full-stack developer to build an AI-integrated multi-agent chat platform. The role involves developing both front-end and back-end components, setting up real-time chat functionality, integrating AI agents, and ensuring a smooth user experience. This is a small-scale MVP project with a clear scope. The expected delivery timeline is 2 weeks. Project Overview We need to develop a web-based chat platform where users can create chat rooms and communicate with other users as well as multiple AI agents. The chat should support text messages, document uploads, image uploads, and AI-powered responses. The AI agents may use the same LLM provider, but each agent should have a different role, system prompt, and behavior. Core Functionality Users should be able to: Register and log in using email authentication Use 2FA for additional account security Create chat rooms Add or invite multiple users to chat rooms Send and receive messages in real time Upload documents and images into the chat Interact with multiple AI agents inside the same chat AI Agent Logic The platform should support multiple AI agents. Users can directly call a specific agent using mentions, for example: @agentName please analyze this document If no specific agent is mentioned, a routing/regulator agent should analyze the message and decide who should handle it. The routing agent may delegate the message either to another AI agent or to a human user with a specific role. Each AI agent should have its own configurable role, prompt, and behavior. Technical Requirements The project should include: React front-end Back-end API Database integration WebSocket-based real-time messaging File upload support for documents and images Email authentication 2FA authentication Chat room management User and role management AI provider integration Multi-agent routing/delegation logic Clean and maintainable code Experience with web technologies such as HTML5, CSS, JavaScript, and modern front-end frameworks is required.
