Marek Kačmařík enhanced Azure Key Vault SDKs by enabling dynamic API version resolution and delivering cross-language improvements in the Azure/azure-rest-api-specs repository. Over two months, Marek removed hardcoded API versions from configuration files, allowing Go and Rust SDKs to support multiple API versions and reducing maintenance overhead. He upgraded the Rust Key Vault SDK to support advanced secret and certificate features, such as output content type selection and Subject Alternative Name extensions, while aligning Go client field mappings for improved compatibility. Marek’s work demonstrated depth in API specification, SDK development, and cloud services, resulting in more flexible and future-proof client libraries.

2025-10 Key highlights: delivered cross-language Key Vault enhancements and API upgrades enabling richer secret/certificate operations and smoother client generation. Key achievements include: Rust Key Vault SDK updated to 2025-07-01 with enhanced secret handling (output content type for Get Secret, SecretProperties.previousVersion, SAN extensions for URIs and IPAddresses); Go client field name mappings for SubjectAlternativeNames.uris and IPAddresses in Key Vault Certificates to improve Go client generation; Azure Go SDKs (azadmin, azcertificates, azkeys, azsecrets) upgraded to API version 2025-07-01 with SAN enhancements and previous-version tracking for secrets. Impact: improved flexibility for secrets and certificates, better cross-language compatibility, and reduced integration risk. Skills demonstrated: API versioning, cross-language client generation, SAN/Secret management, Rust/Go ecosystem proficiency, REST spec alignment.
