SYSTEM.ABOUT

RESEARCH FOCUS · MAPF / FLEET

I build the software that lets many robots share one space — planning conflict-free paths, coordinating fleets, and keeping autonomy reliable when the real world gets crowded.

My specialty is Multi-Robot Navigation & Multi-Agent Path Finding (MAPF) — the algorithms and system architecture that turn a pile of independent robots into a coordinated, congestion-aware fleet. I've shipped this from both ends: decentralized coordination running on real warehouse AMRs, and centralized fleet management for autonomous agriculture.

I work across the full stack of a robotics platform — from perception and control on the robot, through middleware connecting robots to backend and frontend, up to the fleet-management infrastructure that orchestrates everyone. I also contribute upstream to the open-source navigation stack the field runs on (ROS2 Nav2).
