Hi, I'm Paul McMahon.

TokyoDev started off with me writing about my own experiences being a developer in Tokyo. As other international developers asked me questions about working here, I wrote articles to answer them. Now TokyoDev has evolved into a site dedicated to helping international developers start and grow their career in Japan.
