Summary
👤
Senior🎓
Top SchoolChia-tze Chang is a data scientist with a decade of analytical experience and 4+ years focused on machine learning and product-driven analytics, currently applying NLP and AI to user feedback at SiriusMindShare Lab. Based in Seattle, he has led growth and personalization efforts at LINE Taiwan—building predictive models and automated pipelines that scaled to 21M+ daily users and doubled conversion metrics—while earlier roles combined ETL engineering, customer segmentation, and real-time reporting to cut CAC and boost satisfaction. He blends hands-on SQL/Python engineering with product intuition, shipping recommendation systems and marketing intelligence tools that materially improved CTRs, revenue, and operational efficiency. An MS in Management Science and formal data science certification complement a pragmatic approach to turning qualitative feedback into quantitative insights. Outside work he balances productivity with family and reading, a habit he humorously notes as “lazy” time management that keeps learning sustainable.
