Apr 1, 2026April 2026: Focused on Docker build CI optimization for the proteinpaint project (stjude/proteinpaint). Delivered changes to streamline CI, improve image provenance traceability, and balance performance with stability. Key decisions included upgrading the Docker Build-Push action, adjusting provenance/SBOM controls, and later restoring stability via a rollback, followed by re-enabling structured provenance mode for better auditability. The work sets a foundation for faster, reproducible builds and stronger compliance posture while keeping CI stable for ongoing development.

Oct 1, 2025Month 2025-10: Delivered a streamlined CI/CD pipeline for stjude/proteinpaint, consolidating build logic into scripts, removing ARM build support, switching authentication to GITHUB_TOKEN, and removing buildx to simplify publishing development containers. ARM64 container builds were stabilized with a bug fix to the development container build script. Redis/TileServer connectivity issues were resolved by refactoring client holders and shard instantiation to pass connection details via object literals. These changes reduced release friction, improved ARM64 reliability, and increased runtime stability for distributed components, delivering tangible business value through faster, more reliable deployments and fewer runtime errors.
