I will build a custom multi agent ai system using langgraph and llms
Sharif
About this gig
I build custom AI agents that actually run in production - not one ChatGPT API call wrapped in a demo.
Most sellers hand you a single prompt. I build multi-agent systems on LangGraph where agents collaborate, check each other's reasoning, and return reliable structured output you can trust.
Real example: I built a diagnostic assistant where three agents (a lead, a skeptic, and a researcher) debate a case inside a Reflexion loop, pull live evidence from trusted sources, and pause for human input before finalizing a report.
WHAT YOU GET
- A custom AI agent or multi-agent workflow (LangGraph / LangChain)
- Tool-calling agents wired to your APIs, database, or documents
- RAG grounding so answers cite real sources instead of hallucinating
- FastAPI backend + optional Next.js UI, Dockerized and deployable
- Full source code, docs, and tracing so you can see every decision
WHY ME
600+ commits as a core engineer on a production AI platform. I ship documented, deployable code - never notebooks.
Message me your use case and I'll tell you honestly if an AI agent is the right fit.

I build AI systems and full-stack web apps that run in production, not demos.
600+ commits as a core engineer on a live AI email platform (2nd of 5 engineers). My own shipped work: a multi-agent medical AI, a codebase assistant that answers with real citations, and a live emergency transport platform.
What I do:
- AI agents and multi-agent systems (LangGraph)
- AI chatbots trained on your documents (RAG)
- Full-stack apps (Next.js, React, FastAPI, Node)
- Docker deployment and CI/CD
I scope honestly and tell you when a simpler approach would serve you better.

FAQ
Do I need an OpenAI or Anthropic API key already?
No. I'll help you pick a provider (OpenAI, Anthropic, or Groq for a free-tier-friendly option) and set up keys and billing during the build.
What's the difference between an AI agent and a chatbot?
A chatbot answers messages. An AI agent takes actions — calls your APIs, queries databases, runs multi-step workflows, and decides what to do next. If you only need Q&A over documents, tell me and I'll point you to my cheaper RAG chatbot gig instead.
Can you integrate this with my existing app?
Yes. I can expose the agent as a REST API your current frontend or backend calls, or build the full stack if you don't have one.
What if I don't know what agents I need?
Describe your workflow in plain English in the requirements form. I'll propose an agent architecture before writing any code.
