Stijn Berend developed two major data-export features for the runelite/plugin-hub repository, focusing on enhancing reliability and automation capabilities. He implemented a safety mechanism in Java to disable connections to revoked URLs upon HTTP 401 responses, reducing unnecessary network requests. Stijn also improved data accuracy by refining coordinate handling and instance-change detection, and introduced new event triggers for Combat Task and Achievement Diaries. His work included updating documentation, adding unit tests, and migrating the codebase to Java 11. Leveraging skills in API integration, plugin development, and unit testing, Stijn delivered deeper analytics and more robust integrations without addressing bug fixes.
