Strong lineup of speakers!-David Heinemeier Hansson
Yehuda Katz is a member of the Ruby on Rails core team, and lead developer of the Merb project. He is a member of the jQuery Core Team, and a core contributor to DataMapper. He contributes to many open source projects, like Rubinius and Johnson, and works on some he created himself, like Thor. Yehuda works for Engine Yard, a Ruby on Rails hosting provider based in San Francisco, California.
José Valim is the lead-developer and co-founder of Plataforma Tec. He started working with Rails in late 2006 and began contributing actively after his Google Summer of Code project in 2009. After his Machine Learning master’s degree in Italy, he’s been flying constantly between Brazil and Poland.
Until Carl Lerche discovered Ruby on Rails in 2005 he thought he would never do web development again. It was Ruby that lured him back into programming and open source development. Currently, he spends much of his time at Engine Yard contributing to Rails, and in his free time, to many side projects.
Jonathan Weiss is a partner and consultant at Peritor in Berlin, Germany. Apart from working on Scalarium, an EC2 management platform that automates provisioning and deployment, he contributes to Rails and Capistrano. He is the creator of the Open Source deployment tool Webistrano.
Joseph Wilk is a member of the core development team for Cucumber. He has been developing for the web for 10 years in both big and small companies and as an entrepreneur. After stints working with Java and Python he finally found Ruby. He now spends his time in-between eating Cucumbers working at Songkick.com. Having more fun than is healthy working as a Software Gardener building web systems and working on open source projects. He suffers from test obsession and has given up hope of any treatment.
Mike Dirolf is a Software Engineer at 10gen, where he works on the MongoDB project. He mainly works on client drivers for Python and Ruby, but also takes time out to talk about MongoDB – he has presented at EuroPython, Strange Loop Conf, RubyEnRails, RuPy and RubyConf as well as at meetup groups in New York City, London, Washington D.C. and San Francisco. Mike received a B.S.E. in Computer Science from Princeton University. Born in Albany NY, Mike currently resides in New York City.
Jarkko Laine was one of the earliest Rails evangelists in Europe, giving presentations about the framework when only few people knew it even existed. He has written two Rails-related books, “Unobtrusive Prototype” and “Beginning Ruby on Rails E-Commerce”.
When not running aimlessly around the woods, Jarkko works as a developer for Wildfire App and as a Ruby and Rails trainer/consultant at his own company, O’Design.
Nizar Jouini is working as a Project Manager at Dodreams. He bumped into Ruby while struggling with PHP and he’s been fascinated by Rails ever since his first 15 minute blog.
When Nizar first joined Dodreams he thought that he’d be working on yet another Rails project but instead he found himself in the crazy world of MMO games.
Tero Parviainen works as a programmer at EfiCode. He discovered Ruby and Rails in 2005, which taught him that it is possible to work as a professional web developer and have fun while doing it. He has since been working on bringing some of the spirit of Rails back to the dark depths of the enterprise. He currently works on a mixture of Java and Ruby projects, and after hours enjoys solving impossible problems with Clojure.
