I’m a Senior Product Data Analyst with 4+ years at Garena Free Fire, where I supported product decisions across product, monetization, trust & safety, and player experience for a global title with ~100M DAU. I turn messy problems into clear analysis and practical recommendations, then partner with product, engineering, and operations to ship changes and measure impact.

Recently, I used PSM-style analysis to reveal survivorship bias in toxic voice reports and helped replace blanket bans with a graded penalty model, reaching 99%+ accuracy and reducing recidivism by 0.5% while supporting a directional 1–2% lift in new-user D7 retention. I also diagnosed a major post-merge latency issue by tracing routing logs, cutting abnormal cross-region matches from 90% to below 5%, and designed an A/B test that reduced severe packet loss by 30%+ for target users—alongside deeper work on combat balance and monetization (e.g., a 28% KD gap finding and a Wukong Skill Skin guardrail that lifted pick rate by 4.8%). I’ve supported teams across SG, VN, IND, and LATAM, mentored 2 junior analysts, and improved consistency through weekly SQL reviews and team SOPs.
