• At NCR voyix which is the new entity that came out of NCR corporation, I specialize in developing and enhancing features for our Digital Banking Web Application, focusing on a report generation microservice and check screening microservice. My key contributions include:
• Cheque Screening Feature: Designed and implemented a feature to detect erroneous checks by comparing bank data with issuer data using Spring (Java), SQL, and JPA.
• Template Creation & Transaction Filtering: Improved the report generation process by developing a robust template creation feature and enhancing transaction filtering capabilities.
• Performance Optimization: Coded REST APIs and reduced cloud storage download times by 60% through parallel execution with Spring Boot and improved upload efficiency with non-blocking async operations.
• Database and Caching: Created and optimized DB schema designs, implemented in-memory caching, and developed a custom singleton design to manage concurrent session creation.
• Leadership: Guided a team of four, overseeing requirement and dependency analysis, coordinating with multiple teams, delegating tasks, and guiding in implementation.
• Code Quality and CI/CD: Enhanced code quality and security by troubleshooting and fixing bugs, addressing vulnerabilities, and increasing code coverage using tools like SonarQube, Whitesource, and others. Undertook and managed multiple deployments on GCP and utilized CI/CD pipelines with GitHub Actions and Argo-CD.
