Designed and implemented a caching layer that intercepts outgoing REST API requests, stores the responses locally, and serves cached data when the device is offline — simulating the server entirely on the client. The cache is parameter-aware, meaning responses are keyed and retrieved based on the specific parameters sent with each request, so the correct cached response is returned for each unique call rather than a single blanket fallback. This allowed the game to remain fully playable without a network connection, with no changes required to the existing request-side code.

The existing REST API response handling used a large switch-case block — each response type required a new case, making the system fragile and difficult to extend. I replaced it with a reflection and dictionary-based dispatch system: response types are registered automatically, and the correct handler is resolved and invoked at runtime without any changes to the response handling code. New response types can be added by defining a handler class — the parser picks them up automatically with zero boilerplate.
