Developed and integrated the RpcFunctionFetcher interface within the VKCOM/kphp repository to manage storage and retrieval of RPC function results, establishing a foundation for modular and robust RPC result handling. The approach decoupled result storage from RPC execution, improving testability, cross-language interfacing, and runtime performance. Work included generating a PHP interface to expose RPC results to PHP-based clients, updating runtime headers, and integrating the new interface into build configurations. Leveraged expertise in C++, PHP, code generation, and TL schema to align the evolving RPC architecture with project requirements, focusing on maintainability and extensibility while delivering a single, well-scoped feature.
