Jeff Casimir has taught thousands of developers, taken nearly a hundred people from “no experience” to professional, and created over a thousand pages of instructional content. In his keynote address, he will talk about training new developers and integrating them into our communities and companies.

Stretching back to 2005, Jeff has more experience teaching Ruby and Rails than anyone in the world. Starting his education career with Teach for America in 2003, he’s taught middle school and high school, co-founded a middle school, and created Jumpstart Lab in 2009, Hungry Academy in 2012, and gSchool in 2013.

Beyond the classroom, Jeff is a prolific speaker delivering keynotes, talks, and workshops at dozens of conferences and user groups in addition to co-organizing RailsConf. He contributes regularly to open source and is among the most active Rubyists on Github. His Draper gem has been downloaded almost a million times, while the open source Curriculum repo has helped hundreds of developers raise their skills.
