Owned trace generation for post-training: built the pipeline producing human-verified agentic trajectories used as SFT data for an open-weights LLM, and contributed to the broader post-training effort (SFT, distillation, LoRA) on Google Cloud. Built and maintained the LLM evaluation framework, a human-verified agentic benchmark with full LangSmith tracing, used to compare frontier models; trace-level failure analysis drove targeted fixes that improved correctness across models. Re-architected the production multi-agent harness (LangGraph, LangSmith), reducing token usage and end-to-end latency.
