Chen Z.

I build complete web products—from technical architecture and frontend interfaces to backend services, databases, cloud infrastructure, and deployment. With React, Next.js, and TypeScript, I help turn product requirements into working applications, CMS platforms, and interactive media systems. You can bring me in to deliver a scoped application, take ownership of a feature across the stack, or improve an existing system. My experience spans both product development and the infrastructure needed to operate and maintain it. What I can help you build: • Application architecture: define system boundaries, data flows, integrations, and a practical implementation plan • Frontend: React and Next.js applications, dashboards, CMS interfaces, and content authoring tools • Backend and data: Node.js services, APIs, PostgreSQL databases, authentication, and role-based permissions • Cloud infrastructure: cloud functions, cloud storage, media uploads, processing, conversion, and asset delivery • Delivery and maintenance: deployment, integration, troubleshooting, performance improvements, and ongoing technical support Alongside full-stack development, I specialize in 360° and browser-based 3D experiences using krpano, Three.js, and WebGL. This includes custom virtual tours, high-resolution viewers, HLS video playback, interactive maps, and real-time synchronization. At ZOOMLOOK, I developed high-resolution interactive media platforms, content management tools, and supporting asset workflows. My completed Upwork projects include React/Mapbox integration for krpano virtual tours, 360° HLS video work, and custom panorama functionality. I also develop pano-view, an open-source panorama viewer for React and Three.js. Core technologies: React, Next.js, TypeScript, Node.js, PostgreSQL, Drizzle ORM, AWS, krpano, Three.js, React Three Fiber, and Tailwind CSS. I am available around 10–20 hours per week for scoped projects and ongoing part-time collaboration. Share your current setup, the outcome you need, and any constraints. I will help clarify the scope, identify dependencies, and agree on practical deliverables.
