Native Korean Localization QA (LQA) & Senior Software Tester

Korean Native LQA & Linux QA Engineer | App / Game / SaaS Testing I am a Senior Software QA Engineer with over 10 years of experience in the software industry, including 4 years at Symantec. Unlike standard translators, I possess deep technical expertise (Linux, Docker, Python) combined with native Korean linguistic skills. I specialize in Localization QA (LQA), ensuring that your software or game not only reads naturally to Korean users but also functions perfectly without UI/UX glitches. Why work with me: Tech-Savvy LQA: I don't just find typos; I identify hard-coded strings, UI overflows, and functional bugs that pure linguists miss. Proven Reliability: With a background in Enterprise Security (Symantec) and Delivery Management, I understand the importance of deadlines and strict QA processes. Full-Cycle Testing: From creating test plans in Jira to executing regression tests on Linux/Web/Mobile environments. My Services: Korean Localization Testing (LQA) for Games & Apps Functional, Regression, and Compatibility Testing Test Plan & Test Case Creation Bug Reporting & Tracking (Jira/Confluence) Tools & Tech: Jira, Confluence, Linux, Docker, Python, SQL, iOS/Android Testing.
