Re-write and Optimize Process & Pipe Related C Code

I am looking for a freelancer with experience in C coding who can re-write and optimize existing C code related to processes and pipes. The goal is to improve the functionality of the code, which is why I am looking for someone to use a different coding style. In addition, errors that are found during the process should be handled manually. If you have the right experience and knowledge, please contact me today. Thanks!
