What happens when a civil engineer decides to stop waiting for better tools and builds one himself? In this episode, Owen Keenan talks with Sebastian Masset, the creator of HECFlow, a Python-based automation tool for stormwater modelling in HEC-HMS.

They explore how Sebastian transitioned from spreadsheets to scripting, what role AI played in the process, and how any engineer can start bridging the gap between domain expertise and software.
