Based on the analysis, a suitable Chinese nickname would be "中年码农" (Zhōngnián mǎnóng), which translates to "Middle-Aged Software Engineer." Another option could be "赛博浪子" (Sàibó làngzǐ), meaning "Cyber 浪子", which alludes to his engagement with technology, and his slightly cynical, world-weary perspective, with a bit of humor.
