Implements a repository pattern that coordinates between network (Retrofit) and cache (RxCache) layers to fetch outsourcing project data with automatic caching. Features smart key generation that creates cache keys invariant to parameter ordering, ensuring equivalent requests share cache entries. The core logic can be extracted by making context and configuration injectable, removing the BaseApplication dependency for string resources.

Provides two RxJava utility operators: netScheduler() for switching computation to IO thread and observation to main thread (standard for network operations), and notEmptyOrError() for throwing an error when an observable completes without emitting items. These self-contained utilities address common RxJava needs and can be directly reused in any project using RxJava 2+.

Implements a lazy loading mechanism for ViewPager tabs that prevents data loading until the fragment is both visible to the user and has its view fully created. The isolated lazyLoad() method checks visibility and preparation state to avoid unnecessary work, while lifecycle methods properly manage state flags. This pattern can be adapted to other Fragment base classes to improve efficiency in tabbed interfaces.
