The situation
What the project needed.
Cachivache Media was an independent digital culture publication. The app acted as a specialized offline "Pocket", downloading entire editions in seconds when connected, then allowing hours of offline reading.
The work
What I shipped.
- Built a custom offline sync engine scraping and formatting Medium posts for fast local Core Data storage.
- Optimized network payloads for readers facing expensive public Wi-Fi hotspots in Cuba.
- Featured rich typography, tag filtering, full-text offline search, and local reader preferences.
Personal contribution
Technical architecture & leadership.
- Solo developer: parser, Core Data database schema, caching engine, UI layout, and App Store submission.
Outcome & Impact
Results in production.
- Delivered uncensored, reliable digital access to thousands of readers throughout Cuba.
