Worked on the ulta-plus/public repository to deliver firmware update configuration and version management for multiple router devices over a two-month period. Focused on updating configuration files in JSON to ensure devices referenced the latest firmware builds, including models such as Ax1800 and Ax3000. Applied configuration management and version control practices to synchronize firmware metadata, update download URLs, and prepare deployment-ready changes. Tracked all updates through clear commit history, enhancing traceability and operational reliability. The work improved user experience by ensuring devices could reliably access current firmware, with an emphasis on maintaining accurate version references and streamlined upgrade processes across supported hardware.
