What I'm looking for

I seek a senior QA role where I can lead quality strategy, expand automation (JavaScript/Playwright), mentor teams, and drive measurable release improvements in collaborative, engineering-driven environments.

I am a Senior QA Engineer with 11+ years of experience leading quality initiatives for enterprise clients including Google, Amazon, and Oracle. I specialize in cross-team coordination, AI-assisted testing, and process improvement while expanding automation with JavaScript and Playwright.

At dscout I owned quality strategy for AI and Live projects, coordinated testing across 12+ engineers, and established go/no-go release decisions for enterprise clients. I led quarterly bug bashes that caught 15+ critical issues pre-release and reduced potential production incidents by 25%.

I redesigned triage workflows to cut response time by 42% and leveraged Claude Code and GitHub Copilot to diagnose and fix 10+ customer-impacting bugs, improving resolution time by 40% and freeing developer capacity. I present monthly defect analyses to engineering leadership and reallocate testing resources toward high-risk areas.

I mentor QA teams, instituted department-wide quality processes that shortened regression cycles by 30%, and support faster release cadences and higher retention. I hold CSM and CSPO certifications and bring a pragmatic, metrics-driven approach to building resilient, observable releases.
