I worked on the team that built the world's first secure mobile banking application.
In the days before iOS and Android, Monitise MobileATM allowed customers to easily manage bank accounts from mobile devices.
My role was to build an over-the-air provisioning server using Wurfl definitions.
When I joined Monitise it was a 6 person startup based in West London, UK. In 2007 it listed on the London Stock Exchange.
