About
I started in GIS in 2008 and have been building production web applications for more than ten years. Most of my work sits where land, data and software meet: forests, peatland water management, smallholder farmers and commodity supply chains.
I like turning complex requirements into working products quickly, and I am comfortable working independently with remote, English-speaking teams.
