Created Page Object Model frameworks to test search features, real-time messaging, content workflows, and access controls, reaching 85% test coverage and improving overall system reliability.
Developed and executed Playwright automation scripts using Visual Studio IDE with JavaScript and TypeScript for end-to-end web testing
Performed manual testing including functional, regression, system, integration, and UAT testing, ensuring coverage across multiple components.
Used Visual Studio Code extensions including Playwright Test Runner, ESLint, and GitLens for efficient test script development
Identified, logged, and tracked defects using HP ALM and JIRA, working closely with development teams to verify fixes and close issues.
Developed a specialized WebSocket testing framework with Playwright to verify real-time messaging, async events, delivery confirmations, and reconnection logic, maintaining 99.9% stability under load.
Designed automation infrastructure for PayPal's ECM platform, covering document workflows, version tracking, and metadata validation across 400+ test scenarios, boosting testing productivity by 50%.
Applied data-driven testing with TestNG parameterization to validate different user roles, permissions, and messaging flows, and built custom dashboards for better test reporting and traceability.
Built Cypress suites for cross-browser and visual testing, ensuring consistent UI rendering across Chrome, Firefox, Edge, and Safari for global teams.
Built comprehensive end-to-end test suites using Playwright with JavaScript, leveraging modern ES6+ features for maintainable and scalable automation scripts
Created mobile automation scripts using Appium and Java to validate responsive layouts, touch gestures, and compatibility on 15+ devices, including iOS and Android tablets.
Used Jira/Azure DevOps for test planning, traceability, dashboards, and defect management.
Automated document approval processes and permission checks for ECM using Cypress, handling PDF, DOCX, and XLSX formats across enterprise workflows.
Validated AI-driven commerce workflows delivered via PayPal's MCP server and Agent Toolkit by creating repeatable test scenarios for common actions (orders, payments, invoices, disputes, tracking, subscriptions), reducing production defects by establishing confident pre-rollout validation and accelerating agent workflow adoption across pilot teams.
Used Playwright's auto-wait and context isolation features to eliminate flaky tests in single-page apps and improve parallel execution reliability.
Ran network conditiontests with Playwright and Cypress to simulate 3G, 4G, and slow connections, verifying error handling, failover, and auto-reconnect behavior.
Cut overall QA turnaround time by 55% by focusing automation efforts on high-priority regression areas using a multi-tool approach (Selenium, Playwright, Cypress, Appium).
Set up shared test data repositories and reusable libraries, improving framework maintainability by 50% and aligning automation standards across QA teams.
Contributed to backlog grooming and sprint planning, balancing feature, regression, and risk.
