What is your most significant professional achievement recently?

As a QA Automation engineer, my most significant achievement is implementing automated testing in a project from scratch, which reduced regression testing time from several days to a few hours.

I developed a stable set of automated tests using Selenium and integrated them into the CI/CD pipeline, which improved release quality and reduced the number of bugs in production.

Additionally, I optimized test scenarios by removing duplication and improving coverage of critical business functions, which increased team efficiency and accelerated feedback for developers.
