Developed and delivered confidential HTTP capabilities across the smartcontractkit/chainlink-common and smartcontractkit/cre-sdk-go repositories, enabling secure HTTP interactions and confidential data handling for client integrations. Focused on security-centric API design, the work included implementing Confidential HTTP Capability V2, updating dependencies, and generating new protobuf structures to support confidential workflows. Leveraged Go, Protocol Buffers, and gRPC to align cross-repository dependencies and streamline code generation, resulting in a robust SDK and supporting mocks for downstream integrations. The engineering effort strengthened the security posture and broadened use cases for confidential data, while improving developer experience and onboarding for secure HTTP workflows.
