AI Evaluation & Benchmark Engineer focused on LLM Evals, Agent Reliability, and Post-Training.
I build evaluation harnesses, benchmarks, and test datasets to understand where AI systems fail — across reasoning, retrieval, tool use, structured outputs, and multimodal tasks.
My work spans benchmark design, golden datasets, deterministic & model-based evaluation, failure analysis, regression testing, and AI system observability.
I also build Agentic AI and RAG systems, which helps me evaluate them from both sides: how they are built and how they break.
