I’m an ISTQB-certified QA Specialist with 13+ years of experience in software testing across web, mobile, and API applications. I bring strong expertise in manual testing along with hands-on experience in Playwright automation (TypeScript), focusing on improving regression coverage and ensuring stable, high-quality releases. I have worked in both Agile and Waterfall environments, with solid experience in test case design, Requirement Traceability Matrix (RTM), and defect lifecycle management using tools like JIRA and HP ALM. My testing experience includes functional, regression, integration, system, exploratory, UAT, and mobile testing. I am experienced in API validation using Postman, backend data validation using MS SQL, and cross-browser/device testing using BrowserStack. I collaborate closely with developers, product owners, and cross-functional teams to identify defects, perform root cause analysis, and ensure timely resolution. I am currently expanding my automation skills by building test scripts using Playwright (TypeScript) and supporting CI/CD workflows using tools like GitHub Actions and TeamCity. I have exposure to testing applications deployed in cloud environments and understand concepts related to AWS, Docker, and modern DevOps practices. I also follow a risk-based testing approach to ensure critical functionalities are prioritized and well-tested. I collaborate closely with developers, product owners, and cross-functional teams to identify defects, perform root cause analysis, and ensure timely resolution, contributing to continuous quality improvement. Core Strengths: • Manual testing (functional, regression, integration, UAT, E2E) • Playwright automation (TypeScript – POM, reusable frameworks) • API testing (Postman) & backend validation (MS SQL) • Integration testing (React frontend ↔ Node.js backend) • CI/CD integration (GitHub Actions, TeamCity) • Defect management (JIRA, HP ALM) • Agile & Waterfall methodologies • Risk-based testing & test strategy • RTM, test case design & execution • Cross-browser & mobile testing (BrowserStack) • Root cause analysis & quality improvement • Basic exposure to AWS, Docker, DevOps practices
