  • Developed backend logic with Java Spring Boot to manage UI-configurable maintenance windows, with database persistence and real-time notifications via WebSockets and CronJobs. Integrated the BroadcastChannel API to maintain state consistency across multiple browser tabs.
  • Reduced initial load time by 40% through bundle analysis, critical font pre-fetching, and static asset optimization.
  • Built modular, reusable components with Vue.js, TypeScript and Quasar for the SGDEA (Electronic Document Archive Management System), applying complex validations and insurance domain business logic.
