We started with a simple idea—that everyone should be able to accept credit cards—and we've been rethinking buying and selling ever since. 

Buying and selling sound like simple things—and they should be. 

Somewhere along the way, they got complicated. We’re working hard and building a team to make commerce easy for everyone. 

Square Cash is a quick, easy, and free way to send money. The Cash engineering team is responsible for the code that makes this work. We care about infrastructure that makes it easy to write software that is secure, efficient, and tested. We build incrementally with small changes and we deploy to production every day.

• Design data models to support application features
