My technical experience has been in engineering support, large-scale network and system rollouts, node / site commissioning and proof of concept projects, integration and acceptance testing, as well as technical project managing.

On the business end, my responsibilities have covered contract, vendor and product management, as well as technical training and documentation. Working in roles representing both customer and vendor perspectives, I understand both angles of the puzzle.

I enjoy working in cutting edge and new environments and on developing and growing networks.

My working experience has been in work-style/environments based in the USA, UK, several EU countries and in Asia.  I hold citizenship both in the USA and in the EU and am open to projects located (almost) anywhere globally.
