Worked on the lennycolton/vatglasses-data repository to enhance data integrity within the VAT glasses data set, focusing on correcting sector configuration for the CENAMER region. Addressed a data management issue by systematically replacing inaccurate sector ownership values from C2A to C2B across multiple instances in the mg-mh-mn-mr-ms-mz.json configuration file. This update, implemented using JSON and configuration management skills, ensured accurate ownership and sector assignments, directly improving the reliability of downstream analytics and reporting. The work reduced the risk of misattributed ownership, supporting more precise data-driven decisions and maintaining consistency across the configuration management process.
