    • Test Planning, Coverage & Risk: test cases, checklists and exploratory scenarios written from requirements and product risk, with test scope, coverage and priorities
    • Bug Lifecycle & Technical Investigation: bugs identified, reproduced and documented with steps, expected and actual results, severity and evidence, then tracked, verified after the fix and covered by regression — investigated with adb/logcat and Firebase Crashlytics, with analytics events validated on GameAnalytics, Firebase and Roblox Analytics, and APIs tested with Postman
    • Release / Quality Validation: build validation, release readiness, risks and a go/no-go recommendation for Production, with platform and store compliance for Roblox, Fortnite, The Sandbox, the App Store and Google Play, plus compatibility and performance checks across devices from low-end to reference tiers, different screen sizes and resolutions, frame behavior and gamepad controls on PC
    • Cross-functional Work & Process: day-to-day work with QA, developers, producers and other areas on problems, risks, fixes and quality feedback, with improvement suggestions shared as the game evolved; AI used to support test documentation, information organization, research, analysis and test-scenario refinement, including a contribution of small adjustments and improvements to an internal QA tool, with AI and programming as support
