Hi, I'm Brandon Xiang 👋
I’m a web developer focused on frontend engineering, geospatial applications, developer tooling, and practical open source software.
I enjoy turning complex map, UI, and automation problems into tools that are clear to use, easy to maintain, and useful beyond a single project.
🚀 What I Work On
- 🗺️ Geospatial web apps: Leaflet, map rendering, vector tiles, and raster map workflows
- 🧩 Frontend systems: Vue, React, TypeScript, component architecture, and build tooling
- 🛠️ Developer tools: code generation, CLI utilities, workflow automation, and productivity helpers
- 📦 Open source libraries: small, focused packages that solve real integration problems

📊 GitHub Activity
🤝 Collaboration
I’m interested in projects around mapping, frontend infrastructure, TypeScript tooling, and developer experience. If a project helps people build faster or understand spatial data better, I’m probably interested.
