As a QA engineer working on a healthcare application, my responsibilities encompass ensuring the quality and reliability of the software. I perform rigorous testing to verify that all features and functionalities align with the application's intended purpose. This involves conducting thorough manual testing, executing test cases, and analyzing the results to identify any potential issues or bugs. I also collaborate closely with the development team to understand requirements, perform regression testing after bug fixes or feature enhancements, and validate the application's compliance with healthcare industry standards and regulations. By meticulously scrutinizing the application's performance, usability, and data security measures, I contribute to the development of a robust and trustworthy healthcare application that prioritizes patient safety and data privacy.
