I developed enterprise web portals with Java EE using Spring Security, Spring MVC, EJB, CDI, JAX-RS, JAX-WS, JTA, and JPA with Hibernate. I built frontend components with AngularJS 1.2 and Bootstrap and generated PDF and Excel reports with JasperReports.

Beyond feature delivery, I proposed and implemented architectural improvements that increased development productivity and maintainability. I also mentored junior engineers on engineering practices, code quality, and systematic problem-solving.
