  1. 2026/3 — Present · Taipei · Neihu

    QA Engineer (AI Agent Architecture)

    Create Intelligens Inc.

    Solo QA ownership across six product lines — member-engagement platform, LINE CRM, company site (Next.js monorepo), AI virtual-human system (Backend / Brain AI / TTS), and early-stage PoC validation.

    • 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. Git-versioned, auditable, reproducible.
    • Stood up and operates the in-house MeterSphere v3 platform via AI cowork (Test Plan / Case / result writeback / step writeback / screenshot upload / batch update).
    • Wired the full test loop with AI cowork: Jira ticket analysis → test plan & cases → mixed manual + automated execution (Playwright / Midscene) → writeback to test cases and Jira → final test report. Plus QA Filter, QA Weekly Bot (Slack incoming webhook), progress autosave, and work log.
