What’s in a Class?

This is not "sit back and watch slides" — all Jumpstart Lab courses are hands-on. We work with real applications and you’ll implement these tools and techniques yourself. By the end of the class, you’ll have real experience, real skills, and real code to reference.

Who’s this for?

This course is built for developers who feel comfortable with Ruby and Rails or a similar language/framework pair. This course is not for novice developers.

What equipment is needed?

For this session you'll need:
