FAQ
What is the difference between a simple Chatbot and an AI Agent?
A standard chatbot follows a fixed script. The AI Agents I build using LangChain and LangGraph are "reasoning engines." They can plan multi-step tasks, use external tools (like searching the web or querying a database), and make autonomous decisions to achieve a specific business goal.
Why do you use LangGraph for complex business workflows?
LangGraph is the gold standard for high-reliability AI automation. Unlike basic chains, LangGraph allows for "stateful" workflows—meaning the agent remembers where it is in a complex process, can handle loops, and includes human-in-the-loop features for approvals.
Can you build a multi-agent system using CrewAI?
Yes! I specialize in deploying multi-agent teams with CrewAI. I can set up specialized "crews" where one agent acts as a Researcher, another as an Analyst, and a third as a Writer.
What kind of data can my AI Agent access? (Agentic RAG)
Your agent can connect to almost any data source. Using Agentic RAG (Retrieval-Augmented Generation), I can give your agent access to PDFs, Google Drive, SQL databases, or live websites using vector stores like Pinecone or ChromaDB.
Will I be able to integrate this AI Agent into my existing software?
Absolutely. I can deliver your agent as a production-ready REST API using FastAPI. This allows you to integrate your AI automation into your website, mobile app, or internal tools (like Slack, Discord, or Notion) via platforms like n8n or custom code.
Which AI models do you support for these agents?
I build model-agnostic systems. Depending on your budget and needs, I can integrate OpenAI (GPT-4o), Anthropic Claude 3.5, Google Gemini, or even open-source models like Llama 3 or DeepSeek.
