As a QA Automation Engineer at OROS TECH LLC, I designed and executed automated test scripts using JUnit, TestNG, Playwright, Selenium, and Selenium WebDriver. I utilized Java, Python, and JavaScript for comprehensive end-to-end testing of web applications and enhanced IoT device integration. I conducted root-cause analysis to resolve critical bugs, improving software stability. I managed CI/CD pipelines with Jenkins and Docker, and used ADB commands for efficient Android device testing and debugging. I logged defects and performed first-level triage, ensuring high-quality deliverables. I coordinated offshore-onsite teams for effective collaboration and used Jira and Bugzilla for bug tracking and management. Additionally, I utilized Linux commands to enhance testing processes and system management.
