I will develop custom ai agents with langgraph, langchain, tool calling and rag


About this gig
Want an AI agent that DOES the work, not just chats? I build custom AI agents with LangGraph and LangChain that call your tools, APIs and CRM and finish multi-step tasks reliably.
WHAT I BUILD: tool-calling agents (APIs, databases, CRM, email, web search), multi-agent routers and planners, RAG over your documents with memory, human-approval steps for risky actions, FastAPI / Slack / n8n integration, plus logging, retries and cost tracking.
WHY ME: B.Tech in AI & ML (MIT-WPU, Pune) and AI intern at AssetCues, building agentic AI and RAG systems in Python every day.
DELIVERY: scoped milestones, a demo before handoff, source code, README and a Loom walkthrough.
Message me with your use case before ordering and I will map out the agent for free.

FAQ
Which LLMs and frameworks do you use?
LangGraph and LangChain in Python with OpenAI, Gemini or open models. I pick what fits your budget and accuracy needs.
Which tools and APIs can the agent connect to?
Any REST API, database, CRM, email, Google Sheets, Slack or web search. Extra tools can be added as an extra.
Who pays for LLM and API usage?
You do, via your own API keys. I keep costs low with caching, small models for easy steps and cost tracking.
Do I get the source code?
Yes. Source code, README with setup steps and a Loom walkthrough are included in every package.
Can you deploy it for me?
Yes, FastAPI deployment is available as an extra. I can also hand it over ready to run on your server.
