This led to a 33% reduction in return rates and a $6M Growth-Adjusted Contribution Profit. Built using Java, JSP, HTML, Horizonte (Spring-based), and click analytics tracking mechanisms to measure user engagement and optimize rendering efficiency- Upgraded the RDS Core workflow system from Java 8 to Java 17, achieving a 15% reduction in garbage collection (GC) pause times, 12% lower CPU utilization, and 16% reduced heap memory consumption. Enhanced security and compliance by deprecating TLS1.0 and adopting TLS1.2 for stronger encryption and protection against vulnerabilities- Revamped CI/CD processes by creating individual pipelines for 22 AWS-RDS microservice teams, resulting in a 10x increase in release velocity, reduced dependencies, and prevented entire pipeline blockages due to system bugs- Participated in on-call rotations, actively investigating and resolving multiple production issues to ensure smooth operation and system stability- Leveraged AWS CloudWatch to alert the team based on the read/write throttling, disk space, latency anomalies, and error rates of several RDS database systems enabling robustness, enhanced monitoring and reliability of the system.
