Where does the [mathematician - programmer] bachelor go?

I am about to become a bachelor of mathematics at Ural State University and on this occasion I want to share my doubts.
The course with the third people at the lecture began to go much less, many have already worked. At the 4th student there were even fewer students, but I continued neutrality. Firstly, because he was sufficiently involved in extracurricular projects, and secondly, he was convinced that “it is still too early.”
But here, the 4th year exams are coming up and the whole bachelor's degree. We need to decide on something ...
The first step is to understand what I want, but how to do it when almost everything is interesting:

• Bachelor work ~ development of high-level programming language;
• Much and with interest was engaged in web (dhtml, xml, slight) and network technologies in general;
• I am pleased to write both in assembler and C #;
• Now almost everywhere I use perl.

Continue to study in the magistracy, summer programs, perhaps participation in opensource projects - how is it?
So there is no concrete plan for the future yet. Now there are only skills.
I do not think that I am the first one. How do you habracheloveki, found your place?
