About

Robotics-focused engineer with ROS 2 experience who has built and debugged real-time, distributed control/orchestration systems under production-like latency and safety constraints. Led platform changes at Persona for a real-time verification orchestration system using deterministic state machines and async workers, and has hands-on experience stabilizing multi-robot navigation/SLAM behavior using rosbag, RViz, and stress testing in simulation (Gazebo).

Key Strengths

  • Built real-time orchestration layer coordinating multiple services under latency/correctness constraints
  • Designed deterministic state machines to ensure predictable behavior under partial failures
  • Systematic real-time debugging: reproduction/isolation with rosbag + component disabling
  • Performance/timing analysis using RViz and logging to identify inconsistent update rates
  • Validated navigation robustness under stress by scaling robot count and simulating CPU/load worst cases
  • Architected standardized interfaces to support heterogeneous robot platforms while keeping orchestration logic consistent
  • Strong simulation and test discipline (unit/integration/scenario tests) with Dockerized environments
