Yin Yuguang
Ten years of iOS. Eight shipped, three still alive.
Half of it for companies, half for myself.
By day I lead 20-odd people on MiraiMind; the rest of the time I keep FreeLingo and Modian alive.
Backend, ops, design — I do those too. Not out of love; there’s just no one else to do it when you go indie.
