What I'm looking for

I seek a collaborative, Agile team role where I can lead QA automation efforts, improve CI/CD testing pipelines, mentor engineers, and drive measurable reductions in release validation time and defect rates.

I am a Fullstack QA Automation Engineer with extensive experience designing and implementing automation frameworks for backend (Java, RestAssured) and frontend (JavaScript, Playwright) across microservice architectures. I have led QA teams and mentored engineers while improving test scalability, maintainability, and delivery predictability.

I built post-deployment regression pipelines using Jenkins and Concourse, integrated functional E2E and API tests into CI/CD, and leveraged AI-based testing to reduce regression cycles and prioritize defects. My work improved release validation time by 30%, reduced regression cycle time by 23%, and cut defect reproduction time substantially.

I have broad hands-on experience across web and mobile testing, performance testing with JMeter, data validation on Snowflake/PostgreSQL/AWS, and toolchains including Playwright, Selenium, Appium, Cucumber, and Docker. I seek to bring pragmatic automation, quality ownership, and cross-functional collaboration to deliver reliable production software.
