Summary
👤
Senior🎓
Top SchoolSifan Liu is a Lead Product Analyst based in San Francisco with nine years of experience translating data science and experimentation into measurable marketplace impact, having driven $3M+ through end-to-end ownership of optimization efforts. She blends hands-on ML and analytics (Udacity ML nanodegree) with policy-rooted rigor from a Georgetown Public Policy master's, enabling both fast A/B testing and robust measurement frameworks that inform executive roadmaps. At Instawork she built automated root-cause diagnostics and real-time alerting to surface friction for GMs and execs, and previously created ROI frameworks across 20,000+ channels at AWS Startups. Comfortable moving between prototyping (R Shiny), LLM-powered tools for research discovery, and production analytics, she accelerates product decisions under uncertainty. Not obviously: her background in economic policy and international development informs a rare ability to connect macro policy insights to micro product levers for inclusive marketplace growth.
