Summary
🤩
Rockstar🎓
Top SchoolAndrew L is a Senior Data Scientist with a decade of experience turning messy data into high-impact product decisions across startups and large platforms, currently at Shopify in Los Angeles. He has led end-to-end algorithmic work at TikTok that improved DAU, retention, and play duration through rigorous experimentation and causal inference, and has a track record of delivering multi-million dollar opportunities and analytics foundations at ChowNow. Comfortable bridging technical and non-technical audiences, he builds tooling and dashboards that democratize insights (Heap, Tableau) and mentors others in advanced analytics. He also contributes to open-source JavaScript tooling—most notably moving and testing react-i18n inside Shopify’s Quilt monorepo—demonstrating full-stack fluency beyond pure modeling. Collected from consulting to product roles, his work emphasizes actionable simplicity: communicating the right insight clearly often matters more than being maximally complex.
