• Managed sprint planning, reviews, and retrospectives.
• Oversaw multiple projects simultaneously, monitoring development milestones and ensuring quality control compliance.
• Coaching team members, fostering skill development and career growth. Supported one lateral transition and facilitated four promotions within 2 years.

Senior Leader Team Migration goal:

• Created and executed 2-year roadmap for migrating Shopping Cart backend to new service.
• Migration launched on over 20 locales across 160 features owned by different teams on Cart page.
• Migrated 400 million requests per day to new service, resulting in 20% reduction in customer-facing latency.
• Achieved cost savings on backend service team.

API Development and Collaboration:

• Designed and developed Core Cart APIs to enhance customer shopping experience.
• Collaborated effectively with other teams within Retail to migrate traffic from legacy endpoints to new APIs.
• Migrated 66% of AddToCart traffic (over 4 million requests per hour) and all CartCount traffic (over 200 million requests per hour) on Amazon Retail Website to Cart APIs.
• Improved security, resiliency, and consistency on Amazon website.

Infrastructure as Code:

• Led infrastructure as code project to mode, create, and release pipeline infrastructure following operational best practices.
• Successfully encoded 7 Tier-1 pipelines across Cart and Checkout into code.
• Reduced pipeline management time by 90%.

Strategic Planning:

• Collaborated with senior leadership to define requirements and build OP1 and 3-year plan for API-based Cart page and site-wide cart awareness features.

• Designed and implemented metrics visualization system based on Elasticsearch service and Kibana to automate data collection and reporting for 8 Tier-1 release pipelines.
• Improved efficiency of regression testing by designing and implementing approach to streamline mock data regression testing through test step definition and execute automation automatically.
• Coordinated efficient Amazon Shopping Cart application deployments. Achieved CI/CD for Cart release pipeline, resulted in sustained CD status and significant improvement in automation pass rates, from 93% to 99% with executing average 3000 automation test cases per day.
• Introduced auto-generated document outlining feature rendering logic, enabling QA team to comprehend relationships among features, templates, data facets, and service dependencies. This reinforced layered testing, reduced reliance on end-to-end tests, resulting in drop from 75% to 49% in E2E test cases, while increasing percentage of lower-level testing in integration and unit tests.
• Designed enhancements and updates for automation framework running on local and remote platforms.
• Provided direction and guidance to process improvements and established policies.
• Conduct trainings and automation workshop to improve software quality knowledge.

• Checked configuration files and logs to uncover root causes of problems.
• Coordinated regression test automation activities across supported applications.
• Identified and tracked software defects and supported developers in resolving problems by completing additional tests.
• Used open-source tools to develop tools to enhance automation testing efficiency, enables automatic verification, reducing need for manual definition of expected UI behavior.
• Planned and devised cohesive test plans for projects using advanced testing technologies.
• Create resilience testing, including stress and chaos testing. Determined server operating limits with weekly load tests.
• Design and implemented Test Data Service to support over 20 teams automation test data usage.
