Optimize .Net Core Project

Job ID: 34226196

Budget: $30 – $250 AUD

I have a .net core console application which is currently running okay. The main purpose of this app is to call several APIs based on cron schedules, then process the messages and send it to an external source.

What I need is to optimize the code used in the project, handling exceptions in the project as well as keep the API calls under rate limit via applying API throtlling or any other similar mechanims.
