Experience
Product Owner & Lead Game Designer
Jul 2025 — Present
Corochti Studio · Ho Chi Minh City
- Leading game design and product ownership for the studio — sprint planning, backlog, economy design, quest systems, FTUE, and player retention loops.
- Designing all UI/UX mockups and interactive prototypes in Figma.
- Two titles under my design direction reached Top 5 on GameHub 2025 & 2026.
- Inherited a product with no intentional monetization; built the full ad stack from scratch — tripled ARPDAU from day one.
- Redesigned the full ad system (IV/RV pacing, session configs, placement logic) to sustain D30 retention while maximizing revenue — LTV still growing at D30.

Ad Monetization Specialist
Sep 2024 — Jul 2025
VNG Corporation · Ho Chi Minh City — continuing as data analyst & game designer
- Owned ad monetization across 5–10 casual titles (Dead Target, Zombie Hunter, Zombie Fire 3D,...) targeting US, T1 & T3 markets.
- Designed full ad call systems: session configs, IV/RV pacing, first-session delay, placement logic — balancing eCPM, fill rate, and retention.
- Built competitor benchmarking models estimating eCPM, IMPDAU, and LTV from public signals — within 20% of actuals, used by UA for campaign decisions.
- Authored technical integration docs for all network changes and legal compliance (UMP/GDPR); protected ~10–12% of EEA revenue at risk.
- Embedded with UA team as data analyst: built campaign dashboards still actively used today.
