Message

At Personaify, I handle a broad range of everyday product and engineering tasks across the stack, using technologies including Python, Node.js, and PostgreSQL.

At 云从科技 Cloudwalk, I developed the AI2 Platform frontend from scratch and built an image and video annotation system with React-Konva. I also developed the frontend client for a large language model management platform with Next.js and mentored junior developers.

At Dafangya, I refactored a mobile-client frontend and improved performance through code splitting, asynchronous loading, list virtualization, and reducing unnecessary rendering. Earlier, I developed and maintained an Office Automation platform at Dazhagui, created website and Weixin shared-page versions at Jiuhuar, and wrote Python scripts for gene-sequencing analysis at Majorbio.
