About
Robotics software engineer with hands-on experience building ROS2-based distributed multi-robot systems, including task allocation (distance cost matrix) and navigation using Nav2/DWA. Previously on Vicarious’s grasping team, implementing real-world box-picking with vacuum suction and force/torque sensing plus recovery behaviors. Also brings strong engineering hygiene with Gazebo simulation, Dockerized deployments across offices, and GitHub Actions CI/CD with unit/integration testing.

Key Strengths
- Designed multi-layer distributed architecture for multi-robot autonomy (network cluster, global KPI state, assignment layer)
- Built task allocation using distance-based cost matrix for multi-robot assignments
- Implemented obstacle avoidance using DWA via ROS 2 Navigation Stack
- Developed ROS/ROS2 nodes and packages across robot arms, mobile robots, and autonomous driving domains
- Real-world manipulation: grasp planning for boxes in totes with collision avoidance and sensor-based failure detection/recovery
- Debugged navigation accuracy issues via IMU calibration and map updates with iterative validation tests
- Strong deployment/testing practices: Docker-based portability and GitHub Actions CI/CD with unit/integration tests
