Firas Shaari worked on schema management for the Telecominfraproject/wlan-ap repository, focusing on improving the accuracy of network bandwidth metrics in the ucentral-schema’s qos.json file. He identified and corrected the naming of QoS data model fields, updating them from bandwidth_up and bandwidth_down to bandwidth-up and bandwidth-down to better reflect actual data flows. This change enhanced data integrity for network monitoring and SLA reporting across dashboards and analytics pipelines. Firas used JSON and schema management skills to implement and validate the update, delivering a concise, well-documented commit that minimized risk and ensured traceability for future development and maintenance.
