Okay, let’s tackle this. So Will Kiefer has a broad range of skills, including desktop and mobile app development, and experience with languages like Swift, Objective C, and C++. While his skills are valuable, the location is Mazama, Washington, which is a relatively small town. This might put his hourly rate on the lower side compared to larger cities like Seattle or San Francisco. However, considering his expertise, I'll estimate his rate to be around $125 per hour, which is slightly below the national average for software developers in the US. This is also in line with the rate for junior or mid-level developers with similar skill sets.
