Avir implemented end-to-end Custom Credentials Management for IBM’s secrets-manager-node-sdk and secrets-manager-go-sdk, delivering cross-language support for credential lifecycle operations. Using Go, Node.js, and TypeScript, Avir built features enabling creation, deletion, listing, and replacement of custom credentials, including lifecycle control for current and previous versions. The work included updating APIs, SDKs, and integration tests to ensure reliability and alignment across both repositories. By focusing on backend development and cloud services, Avir enhanced security governance and improved credential management workflows. The depth of the implementation is reflected in the comprehensive test updates and the achieved functional parity between the Node and Go SDKs.
