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).
Experience
Education
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
