I build full-stack, graphics, and game systems across web, mobile, and high-performance backend platforms.

I've built production systems across graphics tools, online games, and high-performance backend services in China.

At FESCO Adecco, I developed a node-based 2D motion-effects editor for HarmonyOS, including canvas drag-and-drop connections, glow and deformation nodes, undo/redo, Symbol component re-layout, and Ani interface integration.

At Shenzhen HiFang Network Technology, I delivered game services for transactions, mail, leaderboards, and player profiles using Go, Gin, gRPC, MySQL, and Redis. I also built OpenGL ES 3.0 visual features, third-party login integrations, and Android JNI integration for multiplayer music streaming.

Previously at Duolaima Technology, I improved a search engine's average query response time by 40% and built an Epoll-based IO framework supporting more than 10,000 concurrent connections. I continue building web products including Image Cloud, Muse, and ResumeAI.
