During March 2025, Pav Viswanathan enhanced the rdkcentral/entservices-apis repository by delivering three targeted features using C++ with a focus on API development, error handling, and event-driven design. Pav extended the Run API to accept an appId parameter, enabling app-scoped storage flows through StorageManager integration. He introduced an OnDisconnected event in RDKWindowManager, improving application lifecycle management by supporting event-based disconnection handling. Additionally, Pav improved deinitialization error reporting by updating the IRDKWindowManager Deinitialize method to return Core::hresult, providing clearer failure visibility. These contributions addressed specific business needs and demonstrated depth in both API design and robust error management.
