I stumbled on Drupal on june 2010, at the same time when I put up my own company, focusing on web-development, web-systems and integrations.
I've been a professional software developer since 2001 @ PRESENTOR (http://www.presentor.fi), focusing mainly on the Adobe-platforms, but also built about a dozen web-projects utilizing Apache, PHP and PostgreSQL/SQLite/MySQL.
Drupal was a real found, because I had some foolish-brave plans on creating my own web-CMS, pulling previous experience from a non-web presentation CMS I've built and maintained since 2003, using mainly Adobe Flash/Director.
