About this gig

Looking for an AI agent that actually executes tasks instead of just chatting?


I develop custom, stateful AI agents and automated workflows powered by LangGraph. Whether you need an agent to call external APIs, query internal data, or coordinate a multi-step business process, I build controlled, reliable systems designed to run cleanly.


WHAT I CAN BUILD FOR YOU:


  • Custom Tool Calling: Connect agents to external APIs, web search, or custom business logic.
  • LangGraph Workflows: Multi-step routing, conditional decision-making, and state handling.
  • State & Memory: Persistent conversation context and session history across execution steps.
  • Production-Ready Setup: Clean, modular architecture prepared for smooth local or cloud execution.


WHY WORK WITH ME?


  • Solid Engineering Foundation: Enterprise software engineering background paired with academic research depth in AI systems.
  • Code Quality & Rigor: Clean, maintainable, and well-documented implementation built with long-term reliability in mind.
  • Collaborative Approach: Clear communication and attentive problem-solving to ensure the system fits your operational goals.
