PROFESSIONAL EXPERIENCE:

Amazon, Quality Assurance Engineer II (SDET, A to Z Framework Team)

New York, NY 09/2022 - Present

Product: A to Z

A to Z is Amazon’s internal employee application used by hundreds of thousands of employees globally. As part of the A to Z App Framework Team, I help build scalable automation frameworks that enable high-velocity, reliable testing across web, Android, and iOS platforms.

Designed, developed, and owned the Executor and Reporter modules in Java for Chimera, a GenAI-based automation framework built on Amazon’s ADAM and Nova Act, leveraging LLMs (Claude Models) for natural-language test authoring and intelligent execution across web, Android, and iOS platforms.

Improved test authoring efficiency by 3x through natural-language-based authoring and reusable execution logic, driving increased adoption of the automation framework across multiple teams.

Implemented multi-threaded execution in the Chimera Executor to parallelize web automation test runs, achieving up to 4 faster execution during large-scale regression cycles.

Integrated REST API validation workflows into A to Z’s distributed services, improving cross-service reliability and enabling unified UI and API test execution.

Led end-to-end QA and automation for major A to Z App features, defining test plans, test strategy, and automation coverage, and executing functional, regression, performance, and accessibility testing across UI and backend/service-level workflows to ensure consistent release quality.

Developed and optimized robust automation suites using Selenium (Web) and Appium (Mobile: iOS/Android), achieving ~90% Web and ~70% Mobile Coverage, and reducing overall manual regression effort by ~70%

Built and executed web automation tests using TypeScript and Playwright, validating modern web workflows and complementing existing Selenium-based coverage.

Enhanced CI/CD pipelines by integrating automation with internal AWS-based systems for distributed execution and artifact management.

Leveraged AI agents like Cline and Amazon Q to accelerate boilerplate code and initial documentation drafts, while retaining full ownership of the design, validation, and final review.

MSCI (formerly The Burgiss Group), Senior Quality Assurance Engineer (SDET)

Domain and Platforms - Private Equity, Asset Management Portfolio Management Systems, Analytics API, Data Integration Services supporting large financial datasets

Designed and built a complete automation framework from the ground up using Java, Selenium, Rest Assured, and Cucumber, supporting both Web UI and API testing.

Used the framework extensively to automate functional and regression test suites, achieving 100% API automation and approximately 75% UI coverage.

Reduced manual regression effort by up to 80% through reusable framework components and consistent automation adoption.

Automated validation of complex end-to-end data integration workflows using SQL queries and stored procedures across backend systems.

Validated RabbitMQ-based asynchronous data loading workflows by verifying message queuing, processing, and backend data reconciliation.

Integrated automation into CI/CD pipelines using Maven and TFS, enabling continuous validation and faster feedback.

Mentored offshore QA engineers on framework usage, automation standards, and test reliability.

Owned performance and load testing efforts, designing and executing JMeter-based load tests on on-prem infrastructure and analyzing system behavior under load.
