During April 2026, contributed to the entur/abzu repository by implementing Esri World Imagery as a selectable map base layer, enhancing the visualization of geographic data for end users. This feature was developed using JavaScript and TypeScript, leveraging React and Redux for front end integration and state management. The approach maintained backward compatibility with existing map layers, ensuring minimal disruption to current functionality. By focusing on GIS integration and map rendering, the work improved decision support and user experience while laying the foundation for future basemap enhancements. Collaboration and disciplined version control practices were demonstrated throughout the development process.
