At PHC Global, I own a health-education platform spanning a Flutter app, React admin panel, and Node.js and PostgreSQL API. It supports content authoring, offline delivery, messaging, and reporting.
I built branching-scenario and interactive-content infrastructure with a Riverpod state machine, and designed notification delivery with Firebase Cloud Messaging and persisted records. I also added Socket.IO chat with active-room presence filtering.
I set up automated deployments to a self-managed Linux VPS using GitHub Actions, rsync, nvm, and PM2. I refactored backend services and addressed query and request-lifecycle issues to improve response times and stability under concurrent load.
Earlier at PHC Global, I developed Flutter healthcare and e-learning apps, including Sehat Saheli and EPI E-Learning, and built the organisation's corporate website and CMS on Laravel. At Exxand, I built a data archiving system with Inertia.js, Vue.js, and Laravel.
