• Built a time-synchronized replay and simulation framework for video, sensor telemetry, and perception outputs, enabling engineers to reconstruct and analyze real-world system behavior.
• Developed a 3D virtual navigation environment using Three.js, improving spatial accuracy of rendered vessel trajectories by ~80%.
• Designed a telemetry ingestion and querying layer using InfluxDB, supporting high-volume time-series data replay with live dashboards.
• Created internal debugging tools allowing engineers to scrub timelines, filter perception outputs, and annotate sessions, accelerating root-cause analysis.
• Integrated OTA configuration updates and sensor health monitoring, bridging onboard systems with offboard analysis tools.
