Senior🎓
Top SchoolDror Speiser is a data scientist with nearly a decade of hands-on experience delivering high-performance algorithms in linear algebra, optimization, and statistical inference for production problems. He has built and run large compute clusters, optimized C++ sparse solvers for major speedups, and created end-to-end data and research stacks that scaled a Pagaya investment team from one to over fifty people. Comfortable from low-level signal processing on headphones to large-scale market analysis, he pairs rigorous mathematical training—a master's thesis in the Langlands Program—with practical engineering like mobile battery profiling and interactive geographic visualizations. Dror moves seamlessly between research and implementation, routinely translating academic literature into deployable machine learning systems and operational recommendations. Based in Slovenia, he brings a rare combination of deep theory, extensive optimization expertise, and pragmatic product-minded execution.
