Worked on NVIDIA/cosmos and vllm-project/vllm-omni, delivering three new features focused on autonomous robotics and real-time policy integration. Developed a closed-loop control policy in Python for NVIDIA/cosmos, enabling robots to predict actions based on live observations and goals. Enhanced the Cosmos framework and policy server documentation using Markdown, streamlining onboarding and clarifying integration with DROID systems. In vllm-omni, implemented a DROID OpenPI policy server that streams action chunks over WebSocket, supporting real-time interaction and faster workflows. Emphasized backend development, API design, and system architecture, with a strong focus on maintainable code and comprehensive technical documentation throughout the process.
