Krishna Harsha Puppala

• Lead end-to-end QA testing for enterprise insurance platforms, ensuring quality releases for policy workflows in various Legacy web applications.
• Designed and executed automated regression suites with over 1,000+ automated test cases across critical insurance modules, improving defect detection rate in pre-production by ~30% using Selenium + Cucumber, and reducing regression cycle time by ~50%.
• Led the full testing efforts as sole QA in an Agile team, on Tomcat-based web service front-end (E2E, regression, smoke), based on monthly release cadence, while uncovering critical defects that saved the business operations millions annually in underwriters’ time and resources, and delivered the project on schedule and within budget.
• Led initial test planning for enterprise Legacy App Server migrations (Windows Server version 2016 to 2022) while actively participating in validation efforts of all the pre-prod Databases inside SQL Server (Microsoft SQL Server Management Studio) migrations.
• Enhanced and maintained the automated regression and smoke test suites using Selenium WebDriver with Cucumber BDD (Gherkin) in a Maven-based Java TestNG Automation framework to validate a Springboot + Java PrimeFaces-based UI.
• Performed REST API validation using Postman, including scenario-based verification, payload validation, and response time analysis to ensure data integrity across modern policy rating engines and legacy AS400 systems.
• Collaborated in Agile teams to define acceptance criteria, triage defects, and support UAT sign-offs.
• Maintained and monitored Jenkins continuous integration (CI) pipelines by integrating automated test suites with build pipelines and providing quality gates before deployment.
