Quality Analyst with 5+ years of experience in manual and automated software testing across large-scale consumer technology platforms at Amazon. Skilled in designing and executing end-to-end test automation using Java, Selenium WebDriver, and Playwright, along with functional, regression, API, integration, smoke, and end-to-end testing. Experienced in developing and maintaining reusable automation components, API validation, database validation, defect tracking, root-cause analysis, and CI/CD-based test execution using Amazon Pipelines (Jenkins-equivalent workflows) and Git. Hands-on experience with basic Python scripting for limited testing support activities and AI-assisted development tools such as Amazon Q Developer for code assistance and debugging, and Claude for learning and test-script refinement. WORK EXPERIENCE

Quality Analyst, Amazon July 2021 - Present

Project: Amazon Pay – Payment & Transaction Platform (Apr 2023 - Present) Worked on a digital payments platform supporting secure online transactions, payment processing, refunds, transaction history, multiple payment methods, and backend service integrations. The project focused on validating end-to-end payment workflows, transaction accuracy, API integrations, and reliability across multiple payment scenarios.

• Designed and executed functional, regression, smoke, integration, and end-to-end test cases covering critical payment and transaction workflows.

• Validated successful transactions, failed payments, cancellations, refunds, transaction status updates, payment history, and other business-critical scenarios.

• Performed API testing using Rest Assured and Postman, validating request/response payloads, HTTP status codes, headers, JSON data, and transaction-related business logic.

• Verified integrations between payment services, backend systems, and external payment gateways to ensure accurate transaction processing.

• Automated critical payment workflows using Java, Selenium WebDriver, Playwright, and TestNG, improving regression coverage and reducing repetitive manual testing effort.

• Developed and maintained Playwright-based UI automation using reusable automation components and Page Object Model

(POM) principles.

• Implemented Page Object Model and data-driven testing approaches to improve automation framework maintainability and reusability.

• Created and maintained automated test scenarios covering positive, negative, boundary, and transaction-state validations.

• Performed database testing using SQL queries (SELECT, JOINs, filters) to verify transaction records, payment statuses, and data consistency across integrated systems.

• Validated end-to-end data flow by comparing UI and API results against backend database records after transactions, refunds, and cancellations.

• Used basic Python scripting occasionally for test-data preparation and small testing utilities alongside the primary Java-based automation work.

• Debugged automation failures through issue reproduction, log analysis, test-result investigation, and root-cause analysis.

• Logged, tracked, and verified defects using JIRA and collaborated with developers and cross-functional teams through defect resolution.

• Integrated automated test suites with CI/CD pipelines (Amazon Pipelines; Jenkins-style build, trigger and report workflows) and maintained automation code in Git-based repositories, with code reviews through Crux (GitHub pull-request equivalent).

• Used Amazon Q Developer for code suggestions, debugging, and resolving routine automation issues, and Claude for learning and test-script refinement.

• Reviewed and validated AI-assisted code and test suggestions before incorporating them into automation activities.

• Collaborated with QA, development, and cross-functional teams to understand requirements, identify testing gaps, and support quality throughout the release cycle.

Project: Fire TV Platform (July 2021 - March 2023) Worked on Amazon's Fire TV Platform, a digital media streaming ecosystem delivering OTT content across smart TVs, streaming devices, and mobile applications. The platform supported content discovery, playback, navigation, backend services, and device-app integrations across multiple device types and OS versions.

• Performed manual and automated testing of Fire TV applications across 15+ device models and OS versions, ensuring reliable streaming and navigation experiences.

• Designed and executed functional, regression, smoke, and end-to-end test scenarios covering key streaming workflows.

• Developed and maintained UI automation using Java and Selenium WebDriver for critical application workflows.

• Executed regression test cycles covering 200+ test cases and validated application behavior across multiple devices and OS versions.

• Performed API validation and developed 80+ API automation scripts using Rest Assured, validating endpoints, headers, request/response data, and JSON payloads.

• Validated UI workflows, device software, backend service integrations, and cross-platform communication.

• Logged, tracked, and retested defects using JIRA, collaborating with development teams through the defect life cycle.

• Maintained automation scripts using Git, submitted changes for code review in Crux, and supported automated execution through CI/CD pipelines (Amazon Pipelines).

• Performed cross-device and cross-version testing to identify functional, usability, and compatibility issues. ACHIEVEMENTS

• Recognized for contributions to process optimization and cost-effectiveness through test automation.

• R&R Award (Q1) - Recognized for excellence in Device Management.

• R&R Award (Q3) - Honored as Innovation Champion for building automation tools that improved team efficiency. TECHNICAL SKILLS
