PROFILE
Ihar Kryvanos
Ihar Kryvanos contributed to Snowflake-Labs/sansshell by developing features that enhanced remote command execution, authorization policy management, and authentication workflows. He implemented configurable RPC authorization, custom dial address support for HTTP-over-RPC, and a dry-run mode for policy validation, using Go, Protocol Buffers, and gRPC. Ihar also improved certificate handling by extracting SAN URIs and introduced client connection interceptors to support middleware extensibility. His work included refactoring for maintainability, modernizing CI/CD pipelines, and addressing key parsing bugs to ensure robust backend operations. These contributions deepened the system’s security, flexibility, and operational clarity, reflecting a thoughtful, end-to-end engineering approach.
