Senior🎓
Top SchoolAlex Egg is a Staff Research Scientist based in Amsterdam with 15 years of experience building search, personalization, and recommender systems that ship at scale. He combines deep-learning and information-retrieval expertise with product-focused engineering, driving measurable business impact—from revenue gains via billion-scale BERT ranking and amortized inference to multi-million-transaction improvements through off-policy evaluation and exploration strategies. His work spans LLM retrieval-augmented QA, ANN tuning, unsupervised pretraining for tabular foundational models, and practical counterfactual evaluation methods, with publications and preprints at top venues. A serial founder and early engineer at product-led startups as well as teams at Meta, eBay, and Adyen, he pairs research rigor with hands-on productionization across Python, Java, and GPU ecosystems. Notably, he has a track record of turning experimental models into deployed systems that recover weeks of test time or double-digit millions of transactions annually, reflecting an unusual blend of research depth and operational impact.
