Well, I'm working as a C\C++ programmer here in Spain and I'll start to study a couple of courses with the Open University, luckily I'll get a Diploma in Computing in two years.
I hope that with three years experience as a C\C++ Senior Progammer and a Diploma in Computing I'll be able to get a job in Ireland or UK.
