ABOUT ME

About Me

I'm a Quality Engineer with 7 years of experience building automation solutions that prevent bugs, reduce costs, and accelerate delivery. When I'm not crafting test frameworks, you'll find me gaming, watching anime, or spending time with my family.

What drives me

I believe quality engineering is about empowering teams, not just finding defects. I've reduced test costs by 80%, mentored QA engineers into senior roles, and built automation frameworks that achieve 99% stability across mobile and web platforms.

My approach

Strategic automation backed by solid documentation. I've led cross-platform projects (iOS, Android, Web) using Playwright, Espresso, XCUITest, and WebDriverIO—always prioritizing maintainability and business impact over flashy metrics.

What I bring

  • Cost efficiency: Reduced implementation costs by 50% while increasing coverage to 80%+
  • Leadership: Built career development programs and mentored teams to level up their skills
  • Versatility: Fluent in E2E, API, accessibility (WCAG 2.2), and performance testing
  • Innovation: Exploring AI-powered testing workflows to accelerate QA delivery
