Yuki Fujisaki (aka tnj or rai)

A hacker who loves mobile gadgets from Japan but not a ninja.

Recent project:

  • DeployGate, to eliminate wastes in your daily Android development.

Programming languages that I've ever written 10k+ lines of code (at least) in my life:

  • Java (Android, SWT)
  • Perl
  • PHP
  • C++ (Win32, Windows Mobile)
  • Visual Basic (<= 6.0)

Second place:

  • Ruby (on Rails)
  • Javascript (jQuery)


  • Built (literally) an entire service of DeployGate, from server setup to promotional videos ;)
  • Lead one to five engineers of an Android app development team that develops an app for several millions of users in Japan.
  • Built some web services with Perl, MySQL and memcached that served several thousand of queries per second at peak time.
