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.
