Looking to automate your business with a smart AI agent?

I develop custom AI agents and RAG chatbots using LangChain that can think, retrieve data, and perform tasks automatically helping you save time, reduce manual work, and improve efficiency.

Unlike basic chatbots, AI agents can connect with APIs, tools, and databases to complete real tasks like data retrieval, automation, and decision support.


What I offer:

  • Custom AI agent development using LangChain
  • RAG chatbot with accurate, data-driven responses
  • Integration with APIs, tools, and databases
  • Automation workflows using n8n
  • GPT-powered intelligent decision-making
  • Multi-step task execution (agent workflows)
  • Scalable and production-ready solutions
  • Clean, well-documented source code

Use cases:

  • Business automation AI agent
  • Customer support AI chatbot
  • Data retrieval and analysis assistant
  • Workflow automation (CRM, Google Sheets, APIs)
  • Internal AI assistant for teams


Technologies I use:

Python | LangChain | OpenAI GPT | Vector DB (ChromaDB, Pinecone) | FastAPI | n8n


Send me your idea, and I will design the best AI agent solution for your business.
