I will build your ai agent with langchain langgraph and rag
Sajjad Sindhu
À propos de ce service
Need an AI agent that actually does the work, not just chats? I design and build production multi-agent systems using LangChain and LangGraph, the same frameworks I use on contract work embedded with teams at Apple, Microsoft, and Anthropic (via Turing).
What I build:
- Single or multi-agent systems with a Supervisor routing pattern
- Tool calling, function calling, and live API integrations
- RAG pipelines connected to your documents, database, or knowledge base
- A FastAPI backend so your agent runs as a real service, not a notebook
- Clear documentation so your team can maintain it after delivery
- Workflow automation and agentic integrations with Zapier, Make, and n8n
I have 6+ years as a backend and full-stack engineer, plus hands-on AI work including LLM red-teaming and RL environment engineering for frontier AI labs. I don't just wrap an API call. I think about failure modes, latency, and what happens when a user does something the demo didn't expect.
Message me your use case and current stack before ordering so I can scope it accurately. Let's build something that holds up.

Hey, I'm Sajjad — a Senior Full-Stack Engineer (backend-focused, I like the hard problems) and AI/LLM Engineer with 6+ years of experience.
I build production AI agents (text and voice), RAG pipelines, and multi-agent systems with LangChain/LangGraph. I also build automation workflows with Zapier, Make, and n8n, custom Shopify apps, and backend APIs with Python, FastAPI, Django, and Node.js.
I've done this kind of work on contract for teams at Apple, Microsoft, and Anthropic.
I focus on systems that hold up under real users. Send me your use case and I'll get back with a clear plan.
