I created a video for the primes kata from my understanding of DDD approach. Here is the repo https://github.com/cordoval/kata-primes.
Plese keep in mind I worked already seen the other solution, however under similar principles but with different flow of work and focus. Also I did the work with lots of interruption and and mobilizing on a taxi twice and from remote with bad and 0 wifi access. I used the previous solution a bit as the domain expert and tried to focus on intent.
The vide is taking a long time so when it is up on vimeo I will post a note update on this blog post.
