About
Robotics software engineer who built the perception-to-planning pipeline for an autonomous bipedal robot: synchronized and fused 3D LiDAR + multiple depth cameras in ROS1 (tf2/message_filters) to produce combined point clouds and 2.5D maps, then implemented and benchmarked A*/D*/RRT plus hybrid A* footstep planning in simulation. Also founded a software company and personally owned CI/CD, security checks (CodeQL), and release automation (custom release bot + Slack notifications).
Experience
Education
Key Strengths
- Deep hands-on ROS sensor pipeline work (tf2 transforms, message_filters sync, point cloud merge/publish)
- Diagnosed real-world data issues in ROS1 logging (bandwidth/rosbag drops) and accounted for them in debugging
- Implemented multiple planning algorithms for bipedal navigation (A*, D*, RRT) and evaluated stability (D* most stable in sim)
- Footstep planning with hybrid A* including state modeling (orientation, direction, left/right foot sequencing)
- Reduced hybrid A* search-space explosion by enforcing human-like left/right stepping constraints
- Pioneered footstep planning work in lab, enabling follow-on RL-based multi-terrain walking research
- Strong simulation-first development approach to protect expensive hardware (Gazebo/MuJoCo)
- Built and owned end-to-end CI/CD and release automation as a software company founder (GitHub workflows, CodeQL, release bot, Slack alerts)
