Armin Ronacher started his work in Open Source as a freelance developer for the German
Ubuntu Community portal "ubuntuusers" through which he later became a founding member of the German Ubuntu Association in 2005. While working on ubuntuusers, Ronacher re-discovered the Python programming language and wrote some of the earliest implementations for
WSGI with the goal to write a bulletin board in Python together with Georg Brandl. This board was to be called "Pocoo" and to be a replacement for
phpBB in Python. While the bulletin board never managed a stable release, many other projects appeared out of the Pocoo umbrella project: the Pygments syntax highlighter, the
Sphinx documentation generator, the
Jinja template engine and many other libraries for Python. He also contributed functionality for the Python AST module and the Ordered Dict for Python. After an elaborate April fool's joke where he bundled his libraries in a one-file microframework he decided to create the
Flask web framework. It went on to become one of the two most popular web development frameworks (next to
Django) for Python and the associated libraries found a new home under the "Pallets" community. He also created the Lektor CMS and contributed to a large list of Open Source applications and libraries. He worked for
Plurk, for Fireteam (a game network infrastructure company owned by
Splash Damage), and most recently for the Sentry crash reporting tool. Armin Ronacher is a frequent speaker at Open Source conferences around the world. == Recognition ==
