Worked on the hoodong/2025-2-PLC repository, delivering a documentation-focused enhancement by updating the Class Roster file to include a personal introduction and student ID for an existing entry. This change improved the clarity and completeness of onboarding and audit records without modifying any application logic or introducing new code. Demonstrated careful version control practices by referencing precise commits and ensuring no regressions in functionality. Utilized Markdown for documentation and Git for source control, emphasizing accuracy and maintainability in project records. The work reflected a methodical approach to documentation updates, focusing on data integrity and process transparency rather than feature development.
