Adam Piotrowski's wroclove.rb 2018 lightning talk. Two years earlier, as a less-experienced developer, Adam was amazed at wroclove.rb by DDD, CQRS, and saga patterns. After the conference he dug deeper via blog posts, articles, books and presentations, and later introduced DDD on a new project at his company — a risky decision since no one there had prior DDD experience. Thanks to Arkency's blog posts and the rails_event_store gem, the project succeeded and the team gained benefits out of the box (e.g. an activity/audit-trail log from the event store). Core message: developers need courage, and conferences like wroclove.rb provide crucial inspiration.
