During January 2025, Justin focused on stabilizing data ingestion for the HeatmapLayer feature in the maplibre-native repository. He addressed a persistent issue where earthquake data failed to load by identifying and correcting a broken GeoJSON data source URL. Using Kotlin and Android development skills, Justin implemented a concise, well-scoped fix that restored reliable data loading for users. He also updated documentation references to prevent future regressions, demonstrating careful attention to data integrity and maintainability. While the work was limited to a single bug fix, it reflected strong debugging practices and contributed to improved stability for maplibre-native’s heatmap functionality.
