AI Linguistic QA Specialist | Game LQA | Translation & UI LQA

Game LQA & Localization Specialist and AI Linguistic QA professional with hands-on experience in video game localization, linguistic testing, functional validation, and high-precision AI data evaluation. My working language pairs include EN→zh-TW, EN→zh-HK, zh-CN→zh-TW, and zh-CN→zh-HK, with native Cantonese expertise in Hong Kong game localization. As a trusted freelance partner for ECI Games, NetEase/Youdao, GEEYOO, and other international game localization vendors, I support both Western and Asian gaming titles across PC and mobile platforms. I am also part of international localization vendor pools, including Levsha Localization, supporting Traditional Chinese (Taiwan) LQA for upcoming game projects. My experience spans RPGs, open-world titles, narrative-driven games, simulation and management games, mobile titles, and live and pre-release gaming projects. I work across both localization and in-game testing workflows, from linguistic review and terminology management to hands-on LQA and consistency validation. I also handle large-scale Hong Kong Cantonese game localization and review, taking ownership of localization quality across extensive in-game content. My focus is on ensuring that dialogue, UI, terminology, and player-facing text are not only accurate, but natural, culturally appropriate, and authentic to Hong Kong players. In Game & App Localization QA, I focus on: • In-game Linguistic & Functional Testing (UI validation, text overflow, font/encoding bugs) • Bug Identification & Issue Reproduction (proficient in Jira and client-proprietary bug-tracking tools) • Traditional Chinese localization for Taiwan and Hong Kong, including native Cantonese adaptation • Cultural Adaptation & Transcreation for natural and immersive player experiences • Terminology Management, Translation Review & MTPE • Voice-over & Audio Synchronization QA In AI & Linguistic Projects, I support global language and technology platforms with: • NLI / Contradiction Detection & Textual Logic Review • Transcription Review & Speech/Audio Quality Assurance • Translation Quality Assessment (TQA) & Prompt Evaluation I am highly adaptive to fast-paced environments, urgent testing cycles, large-volume localization projects, pre-release game builds, and strict compliance/NDA requirements. Open to opportunities in Game LQA, Localization Testing, Game Localization & Review, and High-Precision AI Content Evaluation.
