PROFILE
Aleksandr Stepanov
Alexandr Stoyanov focused on CI/CD optimization and DevOps automation across the matter-labs/zksync-era and matter-labs/zksync-os-server repositories. He enhanced CI pipeline performance by introducing a local key cache, reducing setup times and improving throughput, and reconfigured Renovate to group pull requests monthly, streamlining update cycles and reducing maintenance overhead. In zksync-os-server, he optimized resource allocation by moving prover-tests to a dedicated runner label, resulting in faster feedback and more stable builds. His work leveraged YAML, GitHub Actions, and workflow automation, demonstrating a strong grasp of CI/CD best practices and delivering targeted improvements to operational efficiency and reliability.
