👤
SeniorRafael Dias is a Senior Data Scientist and Data Consultant based in São Paulo with nine years of hands-on experience building production-grade backend, ETL and data warehousing solutions and leading cross-functional teams.

Comfortable on both research and delivery fronts, Rafael often translates business roadmaps into reproducible ML pipelines and meaningful feature engineering that directly drive activation and engagement metrics. An English-fluent, international project veteran, he pairs process disciplines (Agile, Lean, Six Sigma, ITIL) with a developer’s sensibility for scalable, optimized systems.
