Can you recall any cool feature you implemented in the last 2-3 months that you are proud of?

Over the past few months, I implemented an automated regression testing system using a CI/CD pipeline. This significantly reduced the time required to verify product stability after each release and improved quality by quickly detecting bugs. For example, I integrated Selenium tests into Jenkins, which run automatically with each commit to the development branch. As a result, the team became faster at responding to errors and reduced the number of bugs in production.
