Alex Macdonald

Worked on the SAP/jmc repository to deliver two core features and address a critical bug over a two-month period. Developed real-time WebSocket-based data streaming for JfrEditor, integrating a WebSocket server and plugin while refactoring the UI to support live data analysis and debugging. Enhanced the JMX protocol extenders for improved compatibility and stability, aligning modules and increasing test coverage to strengthen validation and error handling. Leveraged Java, OSGi, and Eclipse Plugin Development to improve integration reliability and maintainability, enabling faster feedback loops, smoother onboarding of future features, and more responsive user experiences for live data visualization and collaboration.
