Apr 1, 2025April 2025 – Factcast/factcast: Release Readiness via Build System Maintenance. Consolidated housekeeping commits related to build triggers, version bumps, and build/config readiness to prepare the project for the next development cycle. Includes creation and removal of a build.trigger scaffold, version updates across modules, and dependency/build configuration adjustments for release readiness. No explicit major bug fixes were required this period; main focus was to ensure a smooth release pipeline and a clean baseline for the next sprint. Business value: faster, more reliable releases with reduced drift between release and next development version, improved traceability via explicit commit references. Technologies/skills demonstrated: build engineering, version management, CI/CD configuration, dependency management, and repository orchestration.
