Contributed to the hyemi0622/algorithm repository by delivering a Week 1 Hello World Java solution, establishing a clear and repeatable structure for ongoing weekly problem-solving. Focused on feature delivery, the work included preparing cross-language scaffolding with an empty C++ artifact to support future compatibility and onboarding. Demonstrated skills in Java development, repository organization, and disciplined version control, resulting in a runnable Java starter and well-organized file hierarchy. No bugs were addressed during this period, as the emphasis was on laying foundational groundwork to accelerate future contributions and maintain consistency across both Java and C++ workflows within the project.
