• Collaborated with cross-functional teams in an Agile environment throughout the SDLC, designing comprehensive test plans and creating detailed test cases, alongside developing test automation strategies and automated tests, proactively identifying and resolving pre-release issues to ensure effective implementation of end-to-end (E2E), Integration testing, and Regression testing.• Led the development of a Cucumber framework from scratch using Java, Gherkin, Selenium WebDriver, JUnit, and Maven, based on the Page Object Model (POM) design, improving overall testing efficiency by 25%.• Designed comprehensive API testing strategies for REST APIs using Postman and Rest-Assured, validating JSON responses for data accuracy, response times, and error handling. Utilized Splunk for real-time log monitoring and debugging, resulting in enhanced API reliability and performance.• Developed and executed complex Oracle SQL queries and JDBC scripts to validate and ensure data integrity, consistency, and accuracy across multiple database environments, resulting in a 30% reduction in data-related defects in production.• Managed and tracked 1,200 test cases in TestRail, overseeing bugs from identification to verification and eventual closure using JIRA for bug tracking and reporting.• Developed a CI/CD pipeline with Jenkins, integrating Git for version control and deploying Docker containers to staging after successful smoke and regression tests.• Conducted performance testing, including load and stress testing, using JMeter to identify bottlenecks and optimize system scalability and reliability.

• Spearheaded the transition from a TestNG framework to a Playwright framework using JavaScript and the Page Object Model (POM), cutting down test script development time by 30% and enhancing test maintainability across 10+ product modules.• Developed test plans and structured test cases, engaged with team members to specify acceptance criteria, and performed code reviews to confirm test coverage integrity, ensuring alignment with Test-Driven Development TDD practices.• Conducted performance testing using Gatling, identifying and addressing bottlenecks to enhance application scalability and reliability, ensuring optimal performance under varying load conditions.• Executed comprehensive regression and end-to-end testing to ensure software functionality and performance, driving high-quality product releases in a fast-paced Agile Scrum framework.• Implemented relational database testing strategies using PostgreSQL, validating data integrity and consistency across the Claims system.• Cut manual test execution time by 50%, saving approximately 20 hours per week, by developing and implementing a suite of 500+ automated test cases.• Integrated Jenkins for continuous testing, which improved deployment efficiency and guaranteed consistent claim processing quality.
