Full-Stack Enterprise Data Platform

MEVN data platform refactored from academic prototype into production-ready app for Community Health Worker workflows. Rewrote frontend to Vue 3 Composition API + Pinia + Tailwind, replaced static data with dynamic CRUD APIs (Mongoose), added role-based access control (Viewer/Editor), form validation with Vuelidate, and interactive dashboards (bar/donut charts) for client/event metrics. Modular REST design for maintainability.
