About this gig

Need a custom AI agent that can reason, use tools, search your data, and automate real business tasks?


I build production-ready AI agents, RAG chatbots, and LLM applications using Python, LangGraph, LangChain, FastAPI, OpenAI, Claude, AWS Bedrock, and vector databases.


WHAT I CAN BUILD


  • Custom AI agents with tool calling and memory
  • Multi-agent LangGraph workflows
  • RAG chatbots for PDFs, websites, databases, and knowledge bases
  • API, CRM, database, email, and third-party integrations
  • AI workflow automation and business copilots
  • Backend APIs, Docker deployment, and cloud integration


WHY WORK WITH ME


  • 5+ years in software engineering and production AI systems
  • Built an agentic travel platform with booking and itinerary workflows
  • Delivered enterprise RAG over hundreds of documents, reducing KPI lookup time by 60%
  • Clean, scalable code, documentation, and source code
  • AWS, Azure OpenAI, Milvus, PostgreSQL, and hybrid search experience


Every project has different data, integrations, and security needs. Message me before ordering with your use case, data sources, tools/APIs, and deployment environment. I will recommend the right architecture and package.
