Elson Scaria

Java Software Engineer at Charles Schwab

Designed and deployed microservices using Java, Spring Boot, Spring Batch, and J2EE patterns to deliver secure, scalable applications in the banking domain. Built RESTful APIs with Swagger and JSON and integrated React.js and Angular interfaces to enhance multi-platform user experience and consistency. Deployed containerized applications on AWS (EC2, S3, CloudFormation, VPC, Route 53, ELB, Auto Scaling, CodePipeline, CodeBuild) and Red Hat OpenShift (ROSA) using Kubernetes for availability and resilience. Developed CI/CD pipelines using GitLab, Jenkins, Maven, and Gradle, with SonarQube and Nexus for artifact management and quality assurance. Configured AWS API Gateway for routing secure RESTful traffic into backend Lambda and Kafka-based microservices. Implemented batch data processing workflows using Spring Batch for nightly reconciliation and data archiving jobs. Applied unit and integration testing using JUnit and Mockito; enhanced front-end test coverage with Playwright and Seleni

Java Developer at McKesson

Developed healthcare microservices using Java, Spring Boot, JPA, and Spring Batch, supporting backend scheduling and batch imports of claims data. Created and secured REST APIs using JSON and Postman; integrated endpoints with AWS API Gateway for seamless traffic routing. Developed web applications using Angular, TypeScript, and JavaScript to improve front-end responsiveness for clinical portals. Optimized MySQL and HBase queries to support large-scale patient data operations, including indexing and tuning performance. Built Kafka-based data pipelines for real-time synchronization of clinical data across distributed systems. Created full testing stacks using JUnit, Mockito, Selenium, Cucumber, and Playwright for robust regression coverage. Built CI/CD pipelines with Jenkins and GitLab, incorporating Gradle for Java builds and AWS CodeBuild for automated testing in staging environments. Deployed and maintained healthcare applications on Cloud Foundry and Azure cloud platforms, ensuring
