Worked on the Brain-up/brn repository to streamline build configuration and manage dependencies using Kotlin. Focused on technical debt reduction, the developer removed unused Mockito and PowerMock dependencies, aligning the project’s dependency tree with actual code usage. This cleanup reduced artifact size and improved build times, directly enhancing CI reliability and maintainability. By ensuring that Mockito was only included transitively via Spring Test and not redundantly declared, the work minimized potential conflicts and bloat. No major features or bug fixes were delivered beyond this targeted optimization, but the changes contributed to a more efficient and maintainable build process for the project.
