I am an IT engineer in a management and consulting role as partner consultant in a small consultancy, usually doing IT architecture, project management coaching and sometimes even software development and network security.
We specialize in helping managerial and technical people understand each other better - and in firefighting "lost" projects, often for automotive customers, banks and telcos.
I have been in the business for more than 25 years now and left the high speed rat race a couple of years ago, so I am able to do a lot of my work from home - I have about a fifth of my former income now, but it's enough to pay the bills.
Every now and then I will have a fire fighter assignment for a couple of weeks or months when somewhere a project went downhill - that's when I suddenly disappear for a while.
