- Aug 2025 – Jul 2026
- System Architect Intern, Mangoboost [GitHub]
- Worked primarily on system architecture and performance optimization for prefill–decode (PD) disaggregated LLM serving on AMD GPU clusters, focusing on RDMA-based KV-cache transfer, multi-node serving, and ROCm inference paths.
- Improved the MoRIIO serving path across asynchronous KV-transfer completion and cleanup, send draining, READ handoff routing, and multi-node TP=16 prefill–decode execution.
- Made selected upstream contributions to vLLM: AITER MLA/MTP and FP8 correctness, shared-memory broadcast reliability, and MoRIIO proxy health monitoring.
