Worked on modernizing the CI/CD pipeline for the 0chain/gosdk repository, focusing on cross-platform artifact management to improve reliability and streamline releases. Leveraged skills in build automation, GitHub Actions, and workflow management to upgrade the Go version in continuous integration, switch artifact uploads to direct artifacts, and standardize build artifact naming across iOS, Android, and WASM. Addressed platform-specific packaging inconsistencies and removed redundant WASM build workflows, aligning test environments for compatibility. Utilized Shell and YAML to implement these changes, resulting in more stable builds, reduced maintenance overhead, and faster, more predictable release cycles for developers and end users alike.
