Kenta Y.

I help clients test Japanese websites, mobile apps, games, and technical content from the perspective of a native Japanese user with a real IT operations background. I am based in Japan and have 10+ years of experience in network engineering, plus 4 years of experience in internal IT, technical support, and security operations. I can help with: * Japanese website, mobile app, and game QA testing * Japanese localization review and proofreading * UX and usability feedback from a real Japanese user perspective * Bug reports with clear reproduction steps, screenshots, and videos * AI-generated Japanese content review * Japanese review of IT, networking, and security-related content I have completed QA and review projects on Upwork, including web app testing, iOS app testing, Steam game testing, and Japanese statement evaluation. Testing environments available: * iPhone 16 for mobile app and iOS testing * Windows 11 desktop PC for web, software, and Steam/PC game testing * Meta Quest 3 for VR-related testing * Screen recording and screenshot capture I communicate clearly in written English on Upwork, but I prefer written communication over live English calls. I provide clear, actionable feedback to help clients identify issues, improve usability, and increase product quality before release.
