Summary

Andrew Hao joins the panel to discuss a recent talk he gave; he shares his background and his origin story with domain driven design.

Andrew explains what to model as methods and functions in context style mapping. Andrew explains aggregate roots. The panel discusses using these design tools in GraphQL and Phoenix Live View.
