"I’ve seen Grails code you wouldn’t believe …

… or how to properly write maintainable Grails applications"

Over the years, Iván López has built a lot of different Grails applications, and he's learned from his mistakes. As an experienced Grails developer, Iván now possesses a vast amount of knowledge about how to avoid problems and pitfalls in future projects.

For over a year, Iván has been sharing his hard-won expertise with others, so they can benefit from his experience and write more maintainable code that's easy to read and modify.

Join us for this 1-hour webinar to learn valuable tips and strategies for improving your coding practices and developing better Grails applications.

Iván will walk you through code examples and demonstrate how to adapt them to best practices. You'll also see code examples that you should never, ever write, along with alternative solutions that will significantly improve your applications.

Iván says, "I promise no developers were harmed in the making of this talk."


The following topics will be covered:

  • Best practices for writing maintainable and testable Grails applications
  • How to detect bad code and tips for turning it into good code
  • Strategies for avoiding common pitfalls when writing Grails applications


Prior experience building Grails applications is strongly recommended in order to get the most out of this webinar.
