Worked as a process engineer for a long time and eventually as an analyst.
To make things easier, I do MS office automation through vba (eg. create add-ins, UDF and other cool stuff)
I mostly work on Excel so you'll see me around working on questions tagged excel,excel-vba and excel-formula.

I also work on sql-server-2008 and sql-server-2012 but there are a lot of people in this site much better than me on these tags so I prefer learning from them instead :)
