(2023-07 - 2025-01)

• Designed and implemented scalable UI, API, and performance testing frameworks using Playwright (TypeScript), Selenium WebDriver (Java), Cypress, and Python (Pytest/Locust) for enterprise-grade multi-platform applications.
• Led performance and load testing initiatives using JMeter and Locust (Python), establishing performance baselines, identifying bottlenecks, and validating system scalability under peak load conditions.
• Authored Python-based Locust scripts for realistic user simulation in stress, spike, and endurance test scenarios, integrated into Azure DevOps pipelines for continuous performance validation.
• Led the migration of legacy Selenium-based automation suites to Playwright, significantly reducing flaky executions and improving regression execution speed through parallel test execution strategies.
• Developed robust End-to-End (E2E), regression, smoke, integration, and performance automated test suites aligned with Agile delivery cycles and continuous integration practices.
• Architected reusable automation components using Page Object Model (POM), centralized test utilities, reusable fixtures, and data-driven testing approaches to improve maintainability and scalability.
• Integrated automated test suites into Azure DevOps CI/CD pipelines, enabling continuous testing, rapid feedback loops, and shift-left quality validation during deployments.
• Executed API validation and backend integration testing using Postman and SOAP UI, ensuring data consistency between frontend, middleware, and database layers.
• Performed cross-browser validation, defect root cause analysis, and detailed failure debugging for mission-critical enterprise workflows.
• Mentored QA engineers on Playwright automation best practices, Python test scripting, performance testing methodology, framework design patterns, and modern JavaScript/TypeScript automation strategies.
• Improved regression coverage by more than 40% while accelerating execution times and reducing maintenance overhead across automation suites.
