A few weeks ago, we were considering whether the current approach works for us and how we can improve the workflow. The previous pipeline has not worked well and we decided to create a new one from scratch. I will not be writing about the whole workflow, it is not a part of topic but I'm going to tell you about one specific step in our pipeline.
