With concreteCMS I offer pretty much anything from complete sites to emergency repairs, specialising in advanced development as a service to projects and for my own portfolio of addons. I balance this with my other business as an underwater photographer and journalist. Web and diving work provide a good balance between home and away, especially with global communications.

For support of my addons and themes, please use the 'Get Help' link on the respective marketplace page.

Past Experience

Pretty much everything to do with IT and software engineering at some point: real time, embedded systems, avionics, secure, safety critical, defence, management information, c3i, logistics, kernel ports, cryptography, methodologies, standards and procedures. All roles from programming through to project management, research, project reviews, audits, training and strategic consultancy.
