Hi, I am Yiyi Wang.
I'm a data analyst with a PhD in behavioral data and hands-on experience analyzing user behavior, building dashboards, running A/B tests, and developing predictive models to guide product strategy. I'm skilled in SQL, Python, Power BI, cohort analysis, and experimentation, with a track record of improving retention, forecasting, and conversion through data-driven insights. I'm also experienced in LLM analytics, customer journey measurement, and full-stack dashboard development. Data analyst by day, gamer by night :)
