PROFILE
Aleksandr Stepanov
Worked on CI/CD optimization for matter-labs/zksync-era and matter-labs/zksync-os-server, focusing on improving pipeline performance and operational efficiency. Introduced a local key cache to the zksync-era repository, reducing CI setup time by eliminating remote key downloads and increasing throughput. Adjusted Renovate configuration to group pull requests and switch to a monthly update cadence, streamlining dependency management and reducing maintenance overhead. For zksync-os-server, moved prover-tests to a dedicated runner label, enhancing CI resource allocation and feedback speed. Leveraged YAML, GitHub Actions, and DevOps practices throughout, delivering targeted improvements that resulted in faster, more reliable CI cycles without addressing bug fixes.
