3 tasks in C (shell programming, pipe/socket)

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 6 years. My work is online game developing, and mainly focus on server side, using c++ under linux environment. I used c++ to make many great projects, for example, I made the tools which can convert java files into c++ scripts, of course garbage collection included, this job is very similar to a compiler, and is very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.
