The first two systems I worked with using InterSystems technology were a PDP-11 running M11+ and a VAX 11/750 running M/VX. Too many years ago to count! 😊
Since then I've used most, if not all, InterSystems products up to IRIS and HealShare today.
I'm italian living in Switzerland and I work as Senior Consultant at GAIVOTA consultin SA, we provide professional services for InterSystems and other technologies.
Curiosity: apart from DC, I don't have ANY social account! 😁
