Vasyl Hafych
Senior Data Scientist - Pricing And Opportunity
Munich, Bavaria, Germany
Summary
👤
Senior🎓
Top SchoolVasyl Hafych is a Senior Data Scientist with eight years of experience applying probabilistic computing, Bayesian inference, and advanced optimization to real-world problems in pricing, revenue management, and physics research. Currently at Sixt, he designs dynamic pricing and bid-price optimization systems that integrate scalable algorithms into production, building on prior R&D roles where he developed monotonic splines and normalizing-flow sampling tools at the Max Planck Institute. His toolset spans Julia and Python, open-source contributions (MonotonicSplines.jl, BAT.jl, AHMI.jl) and GPU-friendly implementations that bridge research-grade inference with industrial deployment. He combines deep theoretical expertise—sampling, uncertainty quantification and symbolic computing—with practical high-performance engineering for decision support. Based in Munich, he brings a rare blend of particle-physics rigor and product-focused ML for revenue and demand forecasting.
