Quality Assurance Automation Engineer (SDET)

Zeus Learning

Jun 2024 - Present

Designed and developed Playwright (JS/TS) automation frameworks from scratch using Cucumber BDD, delivering maintainable, scalable test suites across multiple enterprise web applications; additionally contributed to and maintained existing Selenium (Java) test suites. Owned full STLC including test planning, manual testing of complex workflows and edge cases, execution, defect tracking, and sprint reporting to ensure consistent quality across every release cycle. Executed functional, regression, cross-browser, and smoke testing across 5+ web applications and environments, reducing per-sprint manual testing effort by 50%. Built REST API test coverage within UI automation using Playwright and Postman; applied network request/response interception and advanced wait strategies to significantly improve test stability across CI environments. Conducted performance and load testing using Apache JMeter, identifying system bottlenecks before production deployment and providing actionable reports to the engineering team. Leveraged GenAI models (ChatGPT, GitHub Copilot) for accelerating test case generation, debugging, and code scaffolding; drove adoption of AI-assisted QA practices across the team. Integrated accessibility (WCAG) testing using Axe-core and visual regression testing within the Playwright framework, catching UI compliance and rendering issues early. Established CI/CD pipelines using Jenkins, GitHub Actions, and Docker, enabling automated regression runs on every commit and eliminating manual pipeline overhead. Reviewed automation PRs and mentored 4 junior QA engineers on Playwright framework design, BDD patterns, and debugging; analyzed PRDs for gaps during sprint refinement and managed full defect lifecycle in Jira.
