Manmohan Singh

SDET with 5 years of hands-on experience in manual testing, UI/API automation, and automation framework development using Java, Selenium, Playwright, TestNG, and REST Assured.

Computer

Science graduate from NIT Jalandhar. Built and enhanced enterprise-scale Data-Driven and Hybrid frameworks, contributing to 95% automation coverage, reducing regression cycle time, and improving automation stability through CI/CD integration and proactive defect analysis. Experienced in functional, regression, exploratory, smoke, sanity, and UAT testing across web and mobile applications with a strong understanding of SDLC and STLC.

Collaborates closely with a cross-functional Agile teams to identify defects early while mentoring new engineers and conducting code reviews to maintain quality standards.

Project: Next Generation Terminal Operating System (NGTOS) — A mission-critical logistics platform for intermodal freight, container management, yard planning, and gate operations for the largest international intermodal railroad organization.

• Developed and maintained 400+ UI and API automated test scripts using Java, Selenium WebDriver, TestNG, and REST Assured, contributing to 95% automation coverage across critical workflows.
• Designed test cases and executed functional, regression, smoke, and UAT testing across web and mobile applications, while performing cross-browser testing to ensure application quality and UI consistency.
• Performed API testing and validation using REST Assured, leveraging JSONPath for response assertions and data extraction, while implementing schema validation and authentication handling for robust API verification.
• Built and enhanced scalable Data-Driven and Hybrid Automation Frameworks using the Page Object Model (POM) design pattern, improving framework maintainability and reducing regression execution time.
• Implemented reusable automation utilities and shared POM components adopted across multiple internal teams, reducing code duplication and improving development efficiency.
• Identified and eliminated flaky automation scripts, improving execution stability and reducing intermittent pipeline failures.
• Expanded automation coverage for complex UI workflows using Sikuli for image-based validations where standard DOM locators were unavailable.
• Integrated automation suites with Jenkins and GitLab CI/CD pipelines for scheduled regression and continuous testing executions.
• Collaborated with developers, Proxy Product Owners, Automation Leads, and business stakeholders to validate acceptance criteria and ensure sprint deliverables met quality standards.
• Logged detailed defect reports, conducted Root Cause Analysis (RCA), and managed test tracking using Jira, Zephyr, and Rally to minimize defect leakage to production.
• Accelerated team velocity by mentoring 3 new QA engineers, cutting their onboarding ramp-up time in half through targeted debugging workshops and framework walkthroughs; conducted peer code reviews, test case reviews, and KT sessions to enforce QA best practices.
