What is a QA software tester?

QA Software Testers are professionals responsible for ensuring the quality of software applications by identifying bugs, errors, or other issues before a product is released. They design and execute test cases, document results, and work closely with developers to resolve problems. Their goal is to ensure the software meets both functional and user requirements, providing a seamless experience for end users. QA testers use various testing methods, such as manual and automated testing, to verify the software's performance, security, and usability.
