I'm thrilled to apply for the Automation Tester role at your innovative team. With a proven track record of slashing regression test runtime by 63% and reducing escaped defects by 82%, I've accelerated release cadences twofold through robust CI/CD pipelines and test automation expertise.
In my role at QualityLoop, I led the migration of our UI test suite from Selenium to Playwright, dramatically cutting runtimes and eliminating flaky tests that once plagued our workflows. This shift not only boosted team efficiency but also integrated API testing and contract verification to catch issues early, ensuring production stability. By championing shift-left practices, I fostered tighter developer collaboration, embedding quality from the start.
My approach to transforming regression suites into fast, parallelized pipelines has consistently delivered measurable impact, like doubling our release speed without compromising reliability. I track key quality metrics to build confidence in every deployment, aligning automation with broader DevOps goals. These efforts have solidified my reputation in quality assurance and automation across cross-functional teams.
