During March 2025, Hyemi delivered a foundational feature for the hyemi0622/algorithm repository by implementing a Week 1 Hello World Java solution and establishing a cross-language scaffolding structure. The work focused on creating a clear, repeatable file organization and providing a runnable Java starter, which streamlines onboarding and accelerates future problem-solving iterations. Hyemi demonstrated skills in Java development, repository structuring, and disciplined version control, while also preparing for C++ compatibility by including an empty .cpp.save artifact. Although no bugs were addressed during this period, the contribution laid essential groundwork for maintainable, multi-language workflows and consistent future feature delivery.
