PROFILE

Jakub Nowak

Worked on the smartcontractkit/cre-cli repository to deliver secure, scalable private registry deployment and workflow lifecycle management features. Focused on backend and CLI development using Go, the work included implementing GraphQL-enabled private registry deployments with access controls, overwrite prevention, and registry-type based settings. Enhanced error handling and expanded test coverage ensured reliability and maintainability. Additional features included unified commands for pausing, activating, and deleting workflows, as well as enforcing unique workflow IDs and registry-aware hash ownership logic. Addressed a bug to preserve paused workflow states during updates, reducing deployment risks and aligning on-chain and off-chain ownership semantics for smart contracts.

Concise monthly summary for May 2026 focused on the CRE CLI repository (smartcontractkit/cre-cli). Key outcomes include: 1) Feature delivery: Enforced unique workflow IDs during private registry deployments and introduced registry-aware workflow hash owner resolution (off-chain requires public_key; on-chain uses existing derivation). 2) Bug fix: Preserved paused workflow state during updates to avoid unintended reactivation. 3) Testing and quality: Expanded unit tests to cover duplicate IDs and registry-aware ownership scenarios. 4) Impact: Reduced deployment risks, safer updates, and clearer ownership semantics across private registry vs on-chain logic. Technologies: Go, private registry strategy, on-chain/off-chain owner derivation, unit testing. Commits: 0dcaf1de0ce0ddea15a567277badd9ca54980de7; 907b32c80f7fd1cbac64bda0eeabe7f4eafbf89b.
