Technology
I designed Hitpic with Sketch and built the app’s frontend with React Native, a framework for building native iOS apps with JavaScript. For image editing and filtering, I wrote custom Objective-C modules for performance reasons. Frontend state is managed with Redux.
The backend’s built with Ruby on Rails and PostgreSQL. Redis is used for background processing with Sidekiq. I also developed an admin interface with Active Admin for monitoring users, content, and marketing effectiveness. Crashlytics was used for distributing beta testing builds.
