Design and implementation of the AddReplica feature, which allows customers to seamlessly add new regions to their existing keyspaces, expanding replication capabilities. Developed the AddReplica SDK API and integrated AWS CloudFormation, streamlining regional expansion for customers and increasing Keyspaces scalability.• Build & launch the Multi-Region Replication (MRR) feature for AWS Keyspaces, deployed across 16 AWS regions. This enabled global customers to access low-latency, highly-available, managed Cassandra–compatible database services. • Optimized the Time-To-Live (TTL) feature for AWS Keyspaces, reducing in-progress table age by 95.4% and cutting overdue tables across 16 production regions from over 300 to zero. Enhanced feature performance led to a smoother database experience for users.• Significantly improved the Anti-Entropy (AE) operations by addressing false-positive divergence alarms. Refined comparison logic in AE process, reducing the divergence detected table count from 14 to zero, ensuring data consistency across regions.• Full software development life cycle participation, including code reviews, source control management, testing, and operations for highly distributed systems

Amazon is guided by four principles: customer obsession rather than competitor focus, passion for invention, commitment to operational excellence, and long-term thinking. We are driven by the excitement of building technologies, inventing products, and providing services that change lives. We embrace new ways of doing things, make decisions quickly, and are not afraid to fail. We have the scope and capabilities of a large company, and the spirit and heart of a small one. Together, Amazonians research and develop new technologies from Amazon Web Services to Alexa on behalf of our customers: shoppers, sellers, content creators, and developers around the world. Our mission is to be Earth's most customer-centric company. Our actions, goals, projects, programs, and inventions begin and end with the customer top of mind. You'll also hear us say that at Amazon, it's always "Day 1." What do we mean? That our approach remains the same as it was on Amazon's very first day - to make smart, fast decisions, stay nimble, invent, and focus on delighting our customers.
