Okay, let’s tackle this. So Gary Cox has a solid skillset in .Net, C#, and Agile methodologies, which are in demand. He also has experience in software development, integration, and test-driven development. Location is Austin, Texas, which is a growing tech hub. According to national averages, software developers with similar skills in the US can charge around $100-$150 per hour. Considering his expertise and location, I estimate his rate to be around $125 per hour, which is slightly below the average but still competitive.
