Senior🎓
Top SchoolDaria Sorokina is a Senior Staff Machine Learning Engineer with 15 years in industry and deep expertise in eCommerce search, now leading foundation-model efforts at Shopify. She built high-impact ranking systems at Amazon—inventing FirTree and co-launching HydraNet—and led initiatives that drove over $1B in incremental annualized sales while improving online-offline metric alignment. A PhD-trained scientist with prior roles at LinkedIn, Yandex, and CMU, she blends rigorous research instincts with production-first engineering and has a track record of mentoring teams and institutionalizing peer-review practices across large organizations. Her work spans multi-objective optimization, compact first-stage rankers, and practical frameworks for iterative target refinement—skills that make her equally comfortable tuning model coefficients as shaping cross-functional strategy. An experienced conference speaker and program founder, she brings both deep technical authorship and measurable business impact to search and recommendation problems.
