About
Robotics software engineer with deep ROS/ROS 2 autonomy experience across warehouse fleets (Knapp delivery robots and quadrupeds), spanning SLAM, EKF-based sensor fusion localization, Nav2, and behavior-tree mission orchestration. Built a simulation-first testing approach using Isaac Sim Replicator with Dockerized, statistically analyzed repeat runs to catch nondeterminism, and personally owned real-world validation. Also developed a custom UR10 singularity-check ROS node based on manipulability.
Experience
Education
Key Strengths
- End-to-end autonomy stack delivery (mapping, localization, Nav2, mission behaviors) for warehouse robots
- Designed behavior-tree-based mission orchestration with robust recovery/fallback handling
- Built simulation-driven test framework with procedurally generated warehouse scenarios (Isaac Sim Replicator)
- Applied statistical rigor to robotics testing (repeat runs for nondeterminism; distribution/variance analysis)
- Containerized and orchestrated repeatable robotics test runs using Docker (and minikube initially)
- Hands-on real-world validation ownership (localization accuracy, collision avoidance, no-go zones, adverse conditions)
- Created custom ROS node for UR10 singularity proximity via real-time manipulability computation
- Improved multi-robot coordination by enforcing lane-based navigation via costmap masks
