About Me
Until retirement, I worked for an investment bank providing financial advice to the private-sector sponsors of major infrastructure projects. Â 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. Â More recently working in the UK with a small power company providing contracted services to National Grid.
