About this gig
AUTOMATE YOUR BUSINESS WITH CUSTOM AI AGENTS USING LANCHAIN, LANGGRAPH & CREWAI.
Whether you need a lead gen agent, support bot, internal ops tool, I will develop efficient, custom AI Agents and workflow automations using Langchain, Langgraph, Crewai and n8n.
My Services:
- Custom AI Agents: Production-grade agents that reason and execute tasks via GPT-4o, Claude, or Gemini.
- Agentic RAG Systems: Agents that retrieve from PDFs/databases (Pinecone/ChromaDB) and take action.
- Multi-Agent CrewAI Teams: Specialized crews (researcher/analyst/writer) collaborating autonomously.
- LangGraph Stateful Workflows: Complex flows with conditional branching and human-in-the-loop approval.
- Multimodal AI Agents: Agents that process images, PDFs, and text for document analysis or visual Q&A.
- Agent Deployment: Production-ready FastAPI endpoints for AWS, GCP, or SaaS platforms.
- Industry-Specific Agents: Purpose-built for e-commerce, real estate, and research automation.

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.
