Worked on the civika-app repository with a focus on backend development using PHP, addressing code quality and stability concerns rather than introducing new features. The primary contribution involved fixing a lint warning in a Blade template by removing a trailing newline, as well as refining a migration constraint in the mahasiswa table to align with linting standards and prevent future data integrity issues. These targeted improvements enhanced maintainability and reliability of the codebase, supporting smoother CI processes. The work demonstrated attention to detail in code quality, particularly in Blade templating and database migrations, reducing technical debt and minimizing production risk.
