    • Self-designed dual-layer QA Orchestrator: each layer holds its own test memory and workflow playbook. Ironclad governance — release-gate confirmation, self-learning from defects, sensitive-data exclusion from version control, Prod-environment guardrails — auto-synced across agent configs.

    Game QA · Test Lead · Game Designer

    Gamania Digital Entertainment → Chinesegamer International → Next Animation Studio → HAPPYTUK → Digiforce → Bugstech

    The formative years of my QA discipline.

    • Bugstech (2015-2017): Managed a 13+ person card-game QA team (3-shift, peaking at 50 people) — staffing interviews, KPI design, annual reviews, shift scheduling, cross-team coordination, on-site vendor exchange in the Philippines.
    • Digiforce (2013-2014, 1y 9m): Web editor — daily curated iOS limited-time-free and chart-ranking titles, wrote quick reviews and published to the company site and the in-house "Limited-Time Free Games" app. Also planned game-strategy companion apps end-to-end, coordinating with design and engineering on UX, dev, testing, copy, and maintenance.
    • Gamania Digital Entertainment (2009-2011): Lead QA on MapleStory for 2 years; supported version tests for CSO / KartRider / Dragon Nest / Bnb / DNF; acted as test lead for 3 months during a re-org.
    • Earlier rotated through game planning, game analysis, set-top box game dev — broad surface area, all feeding back into test instinct.
