MedSnap — Online Pharmacy

An existing app had grown hard to change; it needed offline resilience and live order updates — without a full rewrite.

Refactored to Clean Architecture (BLoC/MVVM), then layered in offline support, real-time order tracking, and REST/Firebase integration, with analytics and CI/CD for stable releases.

Flutter, Dart, BLoC, Firebase, REST APIs, Hive.

Refactor over rewrite: introduce the architecture incrementally across catalog, prescriptions, and checkout so the app kept shipping the whole time.

You can move a live app to Clean Architecture without stopping the world, if you do it feature by feature.
