Sachin Kumar Goyal

• Designed a high-performance terrain lookup engine using a precomputed lookup table approach, replacing sequential grid traversal and reducing 3D terrain data access time by 90% — enabling real-time simulation performance targets to be met.
• Owned end-to-end design and implementation of RoadRunner's video logging subsystem — built an offscreen OpenGL rendering pipeline that replays simulation logs frame-by-frame and exports MP4 videos at 30–60 fps, enabling programmatic video generation without UI dependency. Shipped to customers to strong positive feedback; extended to support traffic signal state and additional scenario element rendering.
• Designed a fault-tolerant gRPC streaming pipeline for simulation log datasets, implementing intelligent chunking to overcome gRPC message size limits and enable reliable large-scale data transfer across simulation components.
• Built multi-threaded systems to consume and process real-time simulation output with improved reliability across concurrent execution contexts.
• Resolved long-pending critical defects across RoadRunner modules — including crashes, memory leaks, race conditions, export failures, map processing, and lane connectivity issues — addressing cases previously unresolved by the team. Consistently triaged and resolved customer-reported high-priority bugs rapidly.
• Built an experimental natural language scenario authoring agent using Claude Code and custom skill files — converts plain English scenario descriptions into RoadRunner scenario authoring API calls, rendering scenes directly in the tool, demonstrating AI-assisted automation of complex engineering workflows.
• Developed scalable API and UI components in RoadRunner to streamline engineering workflow integration; authored design documentation covering use cases, requirements, and feature architecture for new capabilities.

• Implemented simulation scenario actions including actor teleportation and trajectory following aligned with OpenSCENARIO standards.
• Collaborated with cross-functional teams to align simulation requirements and delivery workflows.
