Django and Mobile Vikings
Allows us to create reliable, complex yet maintainable web applications and sites in no time
Pretty URL’s (E.g. /myviking/credit/)
Makes use of Python, which is more explicit; this gives clarity. Existing code has an easy learning curve.
Powerful templating system with inheritance
Built-in support for internationalization

Django and Mobile Vikings (2)
Django helped us to cope with constantly changing situations (many new features, data model changes, complete rewrites of parts)
Abstraction to external API’s
E.g. support for multiple SMS gateways
Easy and fast deployment
Supports iterative development
Clean, but readable code

Clean code
Models define:
Database tables
Object-Relational Mapper
HTML forms (including basic validation)
a part of the REST API
