I promote Elm and run several projects to make it easier for people to learn it and use it:
Aside from my Elm work, I occasionally create Pluralsight courses for software developers and contribute to powertrip.earth to help speed up the transition to electric vehicles.
In the past, I co-founded a company to visualise geospatial data for the heavy construction industry in order to improve safety and productivity when building roads, tunnels and other infrastructure.
In the more distant past, I worked on a wide range of software, from early mobile applications back in the days of Palm Pilot and Windows CE, to a flight simulator to guidance software for construction machinery like bulldozers, excavators and even self-driving kerb laying machines (which are massive things 4 metres tall!).
