About

I have 6.5 years of hands-on experience in IT, including 3 years as a Front-End Developer and 3.5 years as a QA Engineer, with a mindset that combines both development and testing perspectives. As a QA Engineer, I have experience in Manual Testing, Automation Testing using Playwright (JavaScript), API Testing with Postman, and Database Testing with PostgreSQL. My background as a developer helps me understand system architecture more deeply, which enables me to identify potential issues more effectively and improve overall product quality. I am currently based in Vietnam, but I’m flexible and available to work in your time zone.
