Worked on the 0xPolygonHermez/cdk-erigon repository to deliver unified container image publishing across Docker Hub and GitHub Container Registry, supporting both AMD64 and ARM64 architectures. Leveraged CI/CD pipelines, Docker, and GitHub Actions to standardize image tagging, implementing lowercase owner names and short SHA tags on push for consistency. Developed multi-architecture manifests to enhance reliability and discoverability across registries, while normalizing tags to reduce release friction. The work included a clear commit history documenting changes to the GHCR publishing workflow, making future maintenance easier. Shell scripting and YAML were used extensively to automate and streamline the deployment process throughout the project.
