PROFILE
Drew Pesall
Andrew Pesall spent a year engineering user-facing features and modernizing the nasa/earthdata-search repository, focusing on frontend architecture, state management, and test automation. He migrated Redux state to Zustand, streamlined map UI components, and introduced natural language search with spatial and temporal filtering. Using React, JavaScript, and Playwright, Andrew consolidated test suites, improved accessibility, and enhanced error handling for smoother workflows. He delivered analytics instrumentation, robust end-to-end tests, and refactored legacy code to reduce technical debt. His work enabled faster feature iteration, improved maintainability, and delivered a more reliable, accessible, and data-driven experience for Earthdata Search users and developers.
