David Whitlock developed a scalable kata platform for the JoyOfCodingPDX/KatasWinter2025 and KatasSummer2025 repositories, focusing on modular Java architectures and robust CI/CD pipelines. He established multi-module Maven structures, delivered progressive kata exercises such as FizzBuzz, Leap Years, and Gilded Rose, and implemented pairing workflows to streamline onboarding and collaboration. David applied build automation, batch scripting, and test-driven development to ensure reliable, maintainable codebases. By stabilizing builds, refactoring project structures, and addressing flaky tests, he improved feedback cycles and project clarity. His work emphasized code quality, cross-platform compatibility, and efficient dependency management, resulting in a strong foundation for ongoing development.

Stability-focused month for 2025-08 on JoyOfCodingPDX/KatasSummer2025. Achieved CI unblock and repo cleanup: disabled flaky tests to unblock builds; removed obsolete files to improve maintainability and onboarding. Result: quicker feedback, lower CI noise, and clearer project structure for future work. Skills demonstrated: test stabilization, CI/CD, Java project maintenance.

2025-07: Delivered a scalable kata framework with a consistent project structure, CI-enabled workflows, and progressive kata content. Key deliverables include scaffolds for FizzBuzz and LeapYears, extensive Pair-based exercises (Pairs 3–16) with package renames, Gilded Rose scaffolding and test improvements, and foundational modules (Minesweeper Mob/RPNCalculator) with CI configuration. Major bugs fixed in this period included a Maven POM regression, bringing the build back to green and stabilizing dependencies, and cleanup of misnamed modules (mob3/mob4) to ensure consistency. The result is improved onboarding, reliable builds, and a robust foundation for ongoing kata work.
