I’m a passionate Android developer from Taiwan, focused on building high-quality, maintainable mobile applications. With years of experience in Android development, I specialize in GIS apps, efficient UI design, and seamless backend API integration. I'm always exploring new technologies and enjoy sharing what I learn with the community.

I specialize in integrating GIS features into Android apps with practical use of spatial databases and map services. My experience includes:

• Google Maps SDK for Android: Custom overlays, dynamic markers, route visualization, and user interaction
• SpatiaLite: Local spatial database integration for offline querying and spatial analysis
• WMS / WMTS: Consuming OGC-compliant tile and map services for high-precision raster layers
• MBTiles: Supporting offline map tiles with efficient loading and rendering
