Worked on the Diah082/izin repository to enhance data quality by addressing a data duplication issue affecting IP address metrics. Focused on data management, the developer identified and removed a redundant IP address entry, thereby improving the reliability and integrity of downstream analytics. The solution was delivered as a targeted code patch with a clear commit message, emphasizing disciplined bug fixing and minimal code changes. Although no new features were introduced during this period, the work established a more trustworthy baseline for future development. The approach demonstrated careful attention to data integrity and maintenance, utilizing core data management principles and version control.
