3 years ago I was mostly a C#, COBOL and VB6 developer with a bit of SQL experience. Then I worked on a data warehouse project for almost 3 years. Now I'm back doing C# again, except today I had to fix a SQL security problem because our DBA left last week. I also do business analysis (kind of), database design* and anything else that comes along. Could I set up/maintain an AD group? No. I know nothing about networks either. Do I think I'm a full-stack developer? No, but I'm not convinced they exist.

* I know this is heresy to some, but at least I have been on a course with that in the title 🙂
