About Sandra Rosanne

Sandra Rosanne is a data professional with experience at Boston Consulting Group and the Central Bank of Indonesia, where she built things that actually got used: from real-time policy dashboards tracking digital payment adoption, to uncovering $690M in untracked revenue using data analytics for a major state-owned bank. She\'s currently finishing a Master of Engineering at UC Berkeley (IEOR), researching generative machine learning models, grading graduate machine learning courses, and leading an aviation safety analytics capstone with Woolpert Inc. She tends to end up at the intersection of messy data, interesting models, and decisions that matter. Before Berkeley, she spent a year at BCG translating complex financial analyses into board-ready strategies for a major state-owned bank, and after that led a nationwide monitoring platform build at Central Bank of Indonesia that consolidated data from 46 regional offices into something senior leadership actually wanted to open every morning. She\'s most motivated when the problem is hard, the data is imperfect, and the output changes how a team thinks.
