Summary
👤
Senior🎓
Top SchoolHunan Rostomyan is a Senior Machine Learning Engineer based in Berkeley with 11+ years building production NLP and Generative AI systems that scale. He has shipped transformer-based services at high throughput, led question-segmentation models that improved downstream accuracy by up to 90%, and pioneered tooling and annotation workflows adopted across teams. Comfortable spanning full-stack, MLOps, and research, Hunan reduced evaluation latency from weeks to seconds by using LLMs as automated judges and applied prompt engineering to cut hallucinations while preserving user satisfaction. He combines hands-on model development (PyTorch, Transformers, LangChain) with cross-team leadership and mentoring, and has a track record of turning early-stage prototypes into integrated products—most notably through WriteLab’s integration into Chegg. An understated strength is his ability to operationalize research ideas into low-latency, GPU-backed services that serve thousands of requests per second.
