Zoe Gathercole developed a user-facing progress bar for the ESA application in the IBM/terratorch repository, enhancing transparency for users during long-running tasks. She implemented this feature using React and Node.js, integrating real-time feedback into the front end to reduce confusion and improve the overall user experience. Alongside the new functionality, Zoe updated documentation and performed code cleanup within the same commit, ensuring that onboarding and future maintenance would be streamlined. Her work focused on both delivering a tangible feature and maintaining code quality, laying a foundation for future workflow improvements without addressing bug fixes during this period.
