App Development:
Level 2

A 3-month, project-based programme to build, test, secure and release mobile apps on your own. Start with Dart and a small Flutter business app, build a complete Flutter and Firebase application, then upgrade that same app with tests, advanced features, performance work, a security review, an AI feature and a signed release build ready for the Play Store.

Overview

App Development Level 2 is the complete, job-ready Flutter programme — no prior programming experience needed. In month one you learn Dart, Flutter UI, navigation, forms, state management and Git, and build a Small Flutter Business App. In month two you start and build your main Flutter and Firebase app with clean architecture, REST APIs, Firebase Authentication, Cloud Firestore, Storage, push notifications, analytics and Security Rules. In month three you don't start another app — you make the same one production-ready: unit, widget and integration tests, debugging and code review, search, pagination, offline handling and an admin dashboard, performance profiling, a full security review with App Check, a safe, cost-aware AI feature, and a signed APK and AAB with Play Store listing material. Theory is kept short, every practical is submitted and checked, and you finish with portfolio work that shows depth instead of disconnected exercises, plus a 3-month internship.
