Going deeper into Ruby and Rails in the post-Wagon blues

by Caio Andrade Le Wagon Teacher and Klatchian Coffee Guzzler

About this list

This list is ultimately a reflection of my own experiences growing as a developer. It’s more suitable if your career goal is to be a Ruby developer with a heavy focus on Software Engineering and the Rails stack. It deepens what you're familiar with after finishing Le Wagon.

The golden advice

Build things. If you're practicing by yourself, find a problem you want to solve. Be it a page component you're interested in (a navbar that hides on a threshold) or an entire, but simple, app (a downscaled Evernote clone), it's important to have clear goals and to be able to see the results of your work.
