I will build ai agents and ai chatbots with rag, langchain and langgraph
Darshan Lal
About this gig
Need a custom AI agent or AI chatbot that actually works in production, not just a demo? I build them with LangChain, LangGraph and RAG, and integrate them into your website, app or business workflow.
I'm a forward deployed engineer with 7+ years of full stack experience (React, Next.js, TypeScript, Node.js, Python). I work like part of your team: understand the problem, design the AI workflow, build it and ship it to your users.
What I can build for you:
- AI chatbot for your website or app that answers from your docs, PDFs or knowledge base (RAG)
- AI agents that use tools, call your APIs and automate multi-step tasks
- ChatGPT, OpenAI and Claude API integration into your React, Next.js or Node.js app
- Vector databases: Pinecone, pgvector, Supabase, Chroma
- Evals, guardrails, monitoring and deployment so it stays reliable
Why work with me:
- Clean, documented source code you own
- Clear communication and regular updates
- Focus on real business results, not just prompts
Message me before ordering with your use case and I'll suggest the right package.

FAQ
Which LLMs and vector databases do you work with?
OpenAI, Claude, Gemini and open-source models, with Pinecone, pgvector, Supabase, Chroma or your existing database. I'll recommend the best fit for your budget.
Can you add AI to my existing app?
Yes. I'm a full stack engineer, so I can integrate agents or chatbots directly into your React, Next.js or Node.js codebase and deploy them.
Who pays for the OpenAI or Claude API usage?
API and hosting costs are billed to your own accounts, so you keep full ownership. I'll help you set them up and choose models that keep running costs low.
