Perception
04/2026 – Present- On-vehicle detector deployment — C++ INT8 / FP16 pipeline for RTMDet on TensorRT
- Latency profiling — traced ~50% of INT8 time to NMS; root-caused a 5x Mask R-CNN slowdown
- 2D-to-3D lifting of camera detections with LiDAR projection checks
-
Motion Planning
2024 – Present- Trajectory scoring & filtering for a learning based planner, with a data pipeline to learn the filter parameters
- Automatic evaluation that classifies and ranks bad trajectories to speed up triage
- Safety costs & traffic reasoning — collision and yellow light costs, and inferring occluded traffic lights
-
Integration
2022 – 2023- Vehicle bring-up and triage of the AI and network stack for key demos
- Fleet status web app tracking vehicle usage and AI system health

Robot Arm Collision Check
Tight bounding capsules for arm links from an SVD axis fit, drawn back onto the model in Maya.
Zombies-Infection
2D zombie shooter in C++ and OpenGL; zombies hunt the player with weighted A* on an occupancy grid.
