About
I'm reaidea, a programmer in Beijing. Besides code, I tinker with AI and amateur radio (I built a small app called HAM派). In my spare time it's photography, gardening, calligraphy, painting, and handicrafts. I think good product builders are often generalists. Tech and life don't have to compete; they feed each other.
Technology should be low-friction and broadly accessible.Series & collections →
