THE PERSON BEHIND THE CURSOR
HK · GMT+8Exploration
never stops.
I'm XJJ, a high-school developer based between Shenzhen and Dongguan. I build web products and infrastructure experiments with AI in the loop—and learn by shipping what I wish existed.
My blog is the long-term memory: deployment notes, server routes, interesting discoveries, failed attempts, and the useful answer that finally worked.
