During their two-month contribution to the OpenNMS/opennms repository, Stheleman enhanced authentication robustness and improved UI reliability. They strengthened the whoami service and authentication store using Java and TypeScript, ensuring user data was only set when valid, which reduced login failures and improved security. Stheleman also resolved Content Security Policy issues for map tile providers through configuration updates, lowering operational risk. On the frontend, they streamlined navigation by removing duplicate administration menus and stabilized UI tests with Selenium by introducing explicit waits, resulting in more reliable continuous integration. Their work demonstrated depth in API integration, state management, and UI/UX design.
OpenNMS/opennms – November 2025: Key features delivered include a UI cleanup to streamline navigation by removing a duplicate Administration Menu from templates. Major bugs fixed include stabilizing UI tests by ensuring the breadcrumb visibility is awaited in the Manage Events Configuration flow (UI MenuHeaderIT fix). Overall impact: increased UI reliability, reduced flaky tests, and faster CI feedback, contributing to smoother and more reliable releases. Technologies and skills demonstrated: UI test automation with explicit waits, template-driven UI maintenance, and targeted code cleanup for maintainability. Commit references: 55690da1c6b0160bf5de52a5a6f48c769c8c5aeb (Fix MenuHeaderIT test), 64c617df45fff0942506c73ef2135ffea561d1f8 (Remove duplicate administration menu).
