I'm an author and software development consultant specialising in web, mobile and geospatial data. I've been using PostgreSQL since 2008, working primarily with time series of geospatial data.
I previously 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.
Prior to that 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!).
