• As part of my responsibilities, I successfully optimized a Spring Batch based event-driven pipeline with a throughput of 3.75 million records per hour and an error rate of only 0.1%. I also developed and maintained multiple RESTful APIs that handled 20 million API hits daily, and implemented a caching strategy that resulted in a 23x increase in server query response time.
• In addition, I worked closely with the client team to ensure smooth communication between back-end and front-end components, resulting in a more seamless user experience. I integrated distributed tracing across all components, which improved debugging capabilities and enabled 20% faster identification of root cause problems.
• I also increased code coverage by 55% through the implementation of unit testing and integration testing using JUnit and Mockito. To reduce system outages, I integrated circuit breaker and retry design patterns using resilience4j, which led to a 70% reduction in system outages.
• Finally, I developed a series of services that utilize the Java AWS SDK to integrate with various AWS services including S3, Lambda, SQS and RDS.
