Launched in 2 major regional markets (KR, HKMO) for both Apple Store and Google Play Store
Achieved over 7000+ monthly users
What is this project about?
Luxury customers expect perfection, and this VIP loyalty app had to deliver. Launched across 2 major regional markets on both Apple Store and Google Play Store, we improved the average monthly user count from 500+ to over 7000+, all seeking personalized rewards and exclusive experiences. Leading QA testing meant obsessing over every interaction on iOS and Android—no compromises, especially for a client operating at this large of a scale. Multiple dashboards tracked user activity and system health in real-time, catching issues before customers did. From pre-launch planning to post-release firefighting, the entire journey was a collaboration with Scrum Masters and Product Owners, ensuring every feature aligned with what truly mattered.
Takeaway #1: 🔍 QA is product ownership, not checkbox ticking
Owning the full QA process for a dual-market, dual-platform launch meant being the last line of defence before something reached 7,000+ users who expected it to be perfect.
The shift: treating QA not as a checklist but as understanding the product deeply enough to know where it might break before it does. That mindset changes how you write test cases.
Takeaway #2: 📊 Observability is not optional at scale
Going from 500 to 7,000+ monthly active users is a good problem to have — until something breaks and you have no visibility into what. Building real-time dashboards on Dynatrace, then migrating to Datadog as the platform scaled, was some of the highest-leverage work on this project.
If you cannot see it, you cannot fix it fast enough.
