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, Assembler, 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.

NEW :

February 2019 : German translations updated for Go 1.12:

Since 2016 I have been translating "The Go Programming Language" by Alan Donovan and Brian Kernighan in my spare time. The work is now done. Unfortunatly no publisher has shown an interest yet.
Like for the original work there are some chapters for free:
Preface, Content, Chapter 1, Index

February 2016 : Translation of a Go blog post:
