Rails + Domain Driven Design Workshop

Struggling with finding a direction of refactorings to keep your app maintainable? Legacy codebase driving you nuts and not revealing intention?

The next edition will be held in November 16-17th, 2017 in London, England.

Rails DDD Workshop in London

Make your development team understand principles of domain-driven design. Make them master the most powerful design approach in today world of complex business rules.

We can help you. In Arkency, we’re doing consulting with big clients and big businesses. Techniques to codify domain knowledge in code and working with domain experts in an efficient way is the most valuable consultantancy tool we have in our toolbox. It proved extremely valuable in very advanced and standarized domains like risk management or accounting, as well as more wild domains like selling tickets for events.

Overall it was great to learn a lot of new things there. I like your approach to work and focus on sharing that knowledge with people. I enjoyed discussions we had on different topics. Thank you!

What will you get?

Before the workshop (immediately after the payment):

  • Access to our #workshop-rails-ddd Slack channel at Arkency Slack, where you can feel free to ask questions. It’s an exclusive place, only available to the participants of our workshops
  • A free copy of the “Fearless Refactoring: Rails Controllers” ebook which is a worth read as a preparation to the workshops (in case you own it already - any other book of your choice from our offer)
  • Access to a proper DDD/CQRS/ES Rails application with all the concepts implemented. You can get familiar with it, before the workshop.

During the workshop:

  • Introduction to all the important (from the Rails perspective) DDD concepts
  • Exercises to the workshop application
  • Constant help from the Arkency mentors
  • Opportunity to ask questions regarding DDD
  • Opportunity to ask questions regarding applying DDD in your project at work
  • Work in groups or solo, as you prefer
  • Meet other like-minded people who aim to apply DDD in their Rails apps

After the workshop:

  • Stay at our Slack channel and be able to confirm the correctness of your DDD code
  • Ongoing access to the workshop app repository, with all the updates

During our training attendees will learn about domain-driven design principles, as well as a trending architecture approach which is a go-to choice for complex business domains, called event sourcing. After workshops attendants are going to be able to apply DDD principles in the codebase, know beneficial ways to refactor the app to improve its maintainability and know techniques needed to talk with clients.

During the workshop attendands will be a part of the simulated project with the simple domain. Our experts will ensure everyone will be involved in a process of crunching domain knowledge and applying it to the codebase.

The result of the workshop is a complete app with event sourcing. Attendants will also understand techniques useful for transforming the codebase from the Rails way to DDD app.

This training is planned for two days. Most of the time attendants will spend on writing code and crunching domain knowledge to make it all as practical as possible.
