About Me
Until retirement, I worked for an investment bank providing financial advice to the private-sector sponsors of major infrastructure projects. Examples include the Dartford Crossing, M6 toll road, Quito airport, power generation projects, and various oil and gas pipelines including one that recently got blown up in the Baltic. More recently working in the UK with a small power company providing contracted services to National Grid.
