What I'm looking for

I want to lead QA delivery in an agile environment, owning end-to-end device and OS validation (build, regression, OTA, stability) while partnering closely with developers and cross-functional teams to ship stable releases with fewer critical defects.

I’m a Senior QA Engineer with 4.7 years of experience validating large-scale product and platform releases across the Google device ecosystem, including ChromeOS and Aluminum OS. I lead end-to-end QA delivery for two parallel OS programs, owning stable release readiness through daily build validation, regression cycles, feature validation, and compatibility-focused testing across multiple hardware variants.

I strengthen product quality by driving firmware flashing and OTA upgrade validation, then verifying thermal, stability, performance, and functional readiness. I also design test strategies, cases, execution plans, and validation frameworks, mentor junior QA engineers, and run defect triage sessions with developers to reduce reopen rates and improve resolution speed.
