Senior🎓
Top SchoolDionysia Saratsli is a Prompt Engineer and PhD-trained linguist with eight years of experience applying language science to production-scale LLMs and conversational AI, most recently improving query understanding and customer experience at Amazon and now driving prompt engineering at wingmaite. She blends rigorous experimental design and statistical analysis from her doctoral work with practical NLP engineering—designing annotation schemes, evaluation frameworks, and rule-based components that make dialogue systems more semantically accurate.

Her background in cognitive and developmental language research gives her a rare edge in modeling pragmatic and discourse-level phenomena for real users.
