About this gig

Agent demos are easy. Agents that run every day without looping, calling the wrong tool or burning through tokens are much harder, and that's the part I focus on.


I build AI agents and multi-agent systems in Python with LangGraph and LangChain: explicit state, validated tool calls, persistent memory, human approval where the stakes are high, and a FastAPI service your product can call.


Things I've shipped:

  • A booking agent for restaurants, hotels and spas across WhatsApp, Instagram, Messenger, LINE and web chat, built on LangGraph with nine business tools, replying in English or Thai
  • A five-agent security pipeline that finds vulnerabilities, confirms them in a sandbox, writes patches and opens a pull request
  • Multi-agent deal and entity intelligence for a US music-industry platform, as their AI engineer


What happens after launch matters too. I set up tracing (Langfuse or LangSmith) and an evaluation set built from real cases, so when you change a prompt or a model you can see whether results improved.


Works with OpenAI, Claude, Gemini, AWS Bedrock or local models, deployed on GCP, AWS or your own servers.
