Senior QA Automation Engineer specializing in scalable test frameworks and shift-left quality practices.
GermanyWhat I'm looking for
I am a Senior QA Automation Engineer with over six years of experience building scalable test automation frameworks for large enterprise systems in financial, telco, and data-driven domains. I have strong hands-on expertise in Java and TypeScript and have implemented solutions using Selenium, Cypress, and Playwright.
I integrate automated test suites into CI/CD pipelines to speed releases and improve reliability, and I led efforts that reduced manual regression testing time from one day to roughly 30 minutes. I champion shift-left testing and work closely with cross-functional agile teams to define test strategies early, contributing to API, integration, and performance testing for distributed systems.
I actively explore AI-assisted QA tools to improve test coverage, stability, and feedback cycles, and I bring practical experience with TDD/BDD methodologies, performance validation, and tooling such as Git, Jenkins, CircleCI, and JMeter.
