Worked on the grpc/grpc repository to implement SECP384R1 (P-384) elliptic curve support in TLS key exchange groups, addressing compatibility issues with servers requiring this curve. Using C++ and gRPC, introduced the GRPC_TLS_GROUP_SECP384R1 option to allow explicit curve selection during TLS negotiations, which reduced handshake failures and improved interoperability across enterprise environments. The work focused on secure-by-default configuration and incident triage, aligning the codebase with widely adopted cryptographic standards. This targeted feature enhanced network security and reliability in cross-environment deployments, demonstrating a methodical approach to protocol extension and standards compliance within a complex, security-sensitive codebase.
