I have a C software that needs fixing in its logic

Job ID: 32409510

Budget: $10 – $30 USD

I have a simple app in C for Unix, that is already coded (no need to code), and compiles with no issues, however I am looking for someone to help me refocus the logic in the code, and make it fully working and operational.

To Do list:
client - server socket
copying data and manipulation of arrays
optimize speed
fix file descriptor

Amount: Please don't bid one amount and then ask for another. This is a micro project approximate 300-400 lines of code (already developed)
