Rockstar🎓
Top SchoolRuihao Chen is a Tech Lead in Data Science with nine years of experience building and productionizing machine learning and analytics solutions across major tech and consulting firms including TikTok, Google, Deloitte, and 2K. He holds advanced training in business statistics and analytics and combines strong statistical foundations (GLMs, PCA, clustering) with practical NLP and text-mining experience to automate validation, classification, and targeting workflows at scale. Ruihao has a track record of turning large, messy datasets into efficient pipelines and utilities—several of which reduced processing time by roughly 70%—and has deployed models to serve both product and marketing use cases. Comfortable across Python, R, SAS, SQL, and BI tools, he focuses now on opportunities in Health, Wellness and Fitness where rigorous measurement meets user impact. Colleagues describe him as a hands-on leader who bridges research, engineering, and product, and an unexpected strength is his applied sports-analytics research connecting social media text mining to on-court performance insights. Based in San Francisco, he pairs enterprise experience with a curiosity for practical, reproducible data science.
