Are You looking for an experienced Cobol programmer? Here You are.

I'm a freelance programmer with years of experience in programming IBM mainframes using Cobol, C++, DB2, IMS, CICS etc. I did conceptional work, data modeling, coding, testing and tuning.

Furthermore I have some knowledge about Linux and C++ programming including the usual developement tools.

And what I like best is the new language Go.
