What I'm looking for

I'm looking to lead and build scalable automation, performance, and mobile testing in Agile environments, while mentoring QA teams, improving quality processes, and partnering across engineering, product, and deployment teams.

I've led test strategy and automation for Sony Interactive Entertainment services supporting internal teams and game publishers, using Java, Selenium, Cucumber, REST Assured, and Playwright. I also drove the technical direction toward Playwright for UI and API automation while maintaining Jenkins regression pipelines and AWS resources.

Previously, I led QA automation at Emotive.io for an advertising platform, at AAA of Southern California for auto insurance UI, API, and mobile applications, and at Oberthur for an eSIM application. My work includes performance testing with K6 and JMeter, mobile automation with Appium and XCUITest, API validation, database testing, and production deployment support.

I'm hands-on with test architecture and enjoy mentoring QA teams, reviewing automation and development pull requests, improving coverage, and helping teams deliver quality throughout the software development lifecycle.
