/TESTING WEB, MOBILE & AI-POWERED PRODUCTS
Hello!
I’m Trung Kien Nguyen, a Manual QA Tester based in Ho Chi Minh City, Vietnam, currently working at 1Creators.
I have hands-on experience testing websites, mobile applications, internal administration systems, and AI-powered chatbots across education, e-commerce, entertainment, and creator platforms. My testing work focuses on functionality, user interface, responsive behavior, AI response quality, anti-fraud scenarios, bug tracking, and identifying edge cases that may affect the user experience. I collaborate with developers and product teams to reproduce issues, verify fixes, perform regression testing, and support stable, reliable product releases.
