Worked on the Graylog2/graylog2-server repository to enhance workflow observability by implementing the Rolling Upgrade List Visibility Enhancement. This feature ensured that the upgrade list for datanode upgrades became visible during in-progress states, rather than being limited to node count criteria, thereby reducing ambiguity for operators during rolling upgrades. The approach involved front end development using React and TypeScript, with careful changelog management to document the changes and align upgrade workflow documentation. The work focused on improving user experience for upgrade monitoring, demonstrating attention to both technical implementation and clear communication of changes through updated documentation and changelog entries.
