David de Boer presented on his work with Planidoo, an event organization platform built using Zotonic and other technologies. The current architecture uses two separate APIs and data stacks that interconnect data between Zotonic and other services like Elasticsearch. De Boer discussed potential solutions to streamline the architecture including using Elasticsearch as a single data source or rebuilding the system entirely in Erlang. He also emphasized the importance of building community around new projects through stability, documentation, and approachability.
