Senior🎓
Top SchoolRay Lei is a data scientist with a decade of experience applying machine learning and automation to insurance and financial services across Hong Kong. Currently at QBE Insurance, he builds production-ready analytics, automates BAU workflows with Python and VBA, and contributes to data governance and dashboarding to inform management decisions. His earlier roles combined underwriting domain knowledge with analytics—automating reporting, underwriting performance analysis, and even aviation policy underwriting at Bank of China Group Insurance. Ray holds Distinctions in MSc Financial Mathematics and MSc Computer Science, a blend that supports both rigorous modeling (random forests, clustering, regression) and practical engineering (web scrapers, Tableau). He prefers turning messy public data into actionable insights and documentation, a habit reflected in his bilingual personal site where he shares projects and technical write-ups.
