Cohort & Retention Analyst

I’m Zhen Wei. I analyze user cohorts—tracking retention, churn, and lifetime value across segments—to identify engagement trends and risks. I recommend targeted re‑engagement tactics to boost retention. When off‑duty, I explore behavioral data from my own hobby apps. I believe cohort analysis reveals the long‑term health of your app. My aim is to turn insights into loyalty.
