Oleh Mahurin contributed to the thingsboard/thingsboard-edge repository by enhancing dashboard usability for business users. He updated the dashboard title to display TBEL metrics, enabling immediate visibility of key performance indicators directly in the dashboard header. This solution was implemented through configuration and metadata adjustments rather than direct code changes, reflecting a focus on maintainability and low-impact deployment. Oleh utilized his expertise in ThingsBoard’s configuration management and dashboard customization, working primarily with YAML and JSON for metadata updates. The work addressed a business need for real-time KPI access, though the scope was limited to a single feature without bug fixes during the period.
