I am an experienced full-stack programmer from China. I started programming in 2017 and have mainly worked on enterprise management systems, websites, wechat mini programs, and mobile applications. I have strong programming skills and can independently deliver small projects with high quality. I have Chatgpt Plus and Codex Plus. Vercel is now available in China, allowing users in China to access websites deployed on Vercel at a fast speed. This will undoubtedly accelerate the adoption of Next.js, and I am currently specializing in this technology.
