What I'm looking for

I seek a role where I can drive test automation and quality improvements, work in collaborative remote teams, use RPA and automation tools, and grow into technical leadership while contributing to efficient, reliable delivery.

I am a QA engineer with over nine years of experience delivering functional, regression, integration, and end-to-end testing across web and mobile platforms, fluent in collaborating with international and remote teams. I have automated tests with tools like Playwright, Selenium and UiPath, developed Excel VBA utilities that cut manual work by 80%, and supported voice-enabled platform testing across major devices.

My background includes RPA development, coding in Java, C++ and Python, and working closely with developers to reproduce and resolve issues; I have experience creating test cases, running regression and stability testing, and leading onboarding and sub-lead responsibilities. I communicate effectively in Japanese for most projects and bring a pragmatic, efficiency-focused approach to quality and automation challenges.
