I will build custom ai agents and rag chatbots with langchain and langgraph

I build custom agentic AI for research, support, sales, automation, and internal workflows. Using LangGraph and LangChain, I create AI agents with memory, tool calling, API access, approvals, and reliable multi-step execution.

RAG systems let LLMs answer from your PDFs, websites, databases, or knowledge base. I build RAG systems with LangChain, vector databases, citations, reranking, and guardrails for accurate, context-aware responses.

Yes. I build LLM SaaS apps with authentication, dashboards, subscriptions, APIs, databases, RAG systems, and cloud deployment. Your LLM SaaS app can include custom agentic AI powered by LangGraph and LangChain.

Yes. I use LangGraph for stateful agent workflows, branching, retries, memory, and human approval. I use LangChain for prompts, tools, retrieval, embeddings, and model integrations. Together they power custom agentic AI and RAG systems.

Yes. I connect custom agentic AI to CRMs, databases, Slack, Google services, payment APIs, internal tools, and MCP servers. LangGraph and LangChain handle tool calling, workflow logic, data retrieval, and secure integrations.

build RAG systems with Pinecone, pgvector, Chroma, FAISS, Weaviate, Qdrant, and other vector databases. I also improve chunking, embeddings, metadata filters, hybrid search, reranking, and citations using LangChain.

Yes. I audit and improve existing RAG systems, LLM SaaS apps, LangGraph workflows, and LangChain pipelines. I fix poor retrieval, hallucinations, slow responses, broken tools, weak prompts, memory issues, and deployment problems.

Yes. I deploy custom agentic AI, RAG systems, and LLM SaaS apps on AWS, GCP, Azure, Vercel, Render, Railway, or your server. Deployment can include FastAPI, Docker, databases, monitoring, setup, and documentation.

Please share your use case, users, data sources, APIs, preferred LLM, required features, and deployment platform. For custom agentic AI, RAG systems, LangGraph, LangChain, or LLM SaaS apps, message me before ordering.

No. LLM API usage, hosting, domains, vector databases, and third-party services are paid by the client. I recommend cost-effective tools for your custom agentic AI, RAG systems, LangGraph, LangChain, and LLM SaaS apps.
