Worked on enhancing the CI/CD deployment workflows for the skip-mev/skip-go-app repository, focusing on improving reliability and security across development and testnet environments. Upgraded the GitHub Actions checkout action from version 3 to 4, ensuring more consistent code and artifact retrieval during automated deployments. Introduced refined permissions by adding id-token write and contents read/write access to deployment jobs, which strengthened security and reduced manual intervention. All changes were implemented and validated using YAML within GitHub Actions, with updated documentation and playbooks to support future maintenance. The work resulted in faster, more reproducible releases and a more auditable deployment process.
