Dear Hiring Team,
I am a QA Automation Engineer with over 6 years of experience in web and API testing.
I specialize in Java-based automation (Selenium, Selenide, Playwright) and have hands-on experience with CI/CD pipelines and containerized environments.
I have worked in Agile teams, contributed to improving test coverage, and helped reduce regression testing time through automation.
I am currently open to remote opportunities and relocation within Europe, including Serbia.
I would be glad to discuss how I can contribute to your team.
Best regards,
Sergey Sidorov
