Node.js AI Agent Build

JavaScript, Node.js, Express JS, AngularJS, Typescript, API Integration, Next.js, OpenAI, LangChain, Supabase · I’m kicking off an MVP and need a strong collaborator to bring a production-ready AI agent to life. My preference is to develop the stack in Node.js, wiring the agent to both OpenAI and Anthropic so we can mix and match models as the use-case evolves. Supabase will sit behind everything for auth, data storage and logging.

Scope of work You’ll design the agent’s decision logic, integrate external tools and REST endpoints, and expose the whole flow through a lightweight React or Next.js interface. Clean, well-documented code and clear communication are essential because I plan to iterate quickly after the first release.

Key deliverables • Core agent code in Node.js with LangChain, LangGraph or a comparable framework • Seamless calls to OpenAI and Anthropic APIs with graceful fallback handling • Supabase schema, auth rules and logging pipeline • Simple web UI that triggers agent workflows and displays results • End-to-end tests plus a short walkthrough or demo video

What I value You’ve built AI agents or LLM apps before, can own API integrations end to end, and are comfortable working independently while keeping me in the loop on progress and trade-offs.
