Full Stack Developer at Bank of the West

Developed and maintained single-page applications using Angular 17, implementing lazy loading, custom directives, route guards, and reactive state management. Built module-wide routing, created forms with data-driven approaches, and enhanced UI with Bootstrap components. Designed multi-tier applications with Spring MVC/Spring Boot and microservices; applied Spring MVC, AOP, and IOC, and implemented Spring Security and Spring Integration for security and messaging. Utilized Apache Kafka for asynchronous data exchange between business applications; used Spring Data JPA with Oracle and MySQL for ORM and CRUD operations. Exposed RESTful services, automated CI/CD pipelines with GitLab, Docker, and Kubernetes on AWS, and deployed to EC2. Used AWS Lambda and S3 for data uploads and event-driven processing. Conducted unit tests with JUnit and performance testing with JMeter in an Agile environment.
