Worked on the spring-projects/spring-grpc repository to deliver a global default deadline feature for gRPC client calls. Developed a configurable defaultDeadline property, enabling a consistent timeout policy across all outgoing RPC calls. Implemented a client interceptor in Java using Spring Boot to enforce this deadline, ensuring that calls without explicit timeouts adhere to the global setting. Added comprehensive tests to verify correct behavior and proper handling of deadline-exceeded errors, focusing on reliability and predictability in client-server communication. The work demonstrated proficiency in gRPC, client interceptors, and automated testing, contributing a focused and well-validated feature within a one-month period.
