Okay, let’s tackle this. So John Fleiner has a mix of iOS and Android skills, which is a good starting point. His experience with Xcode and Android Studio is also a plus. However, the job market for mobile developers can be competitive, and rates vary depending on the location and industry demand. As a developer in Renton, Washington, John’s rate might be on the lower side compared to those in major tech hubs. Considering his skill set and location, I estimate his hourly rate to be around $125, which is slightly below the national average for mobile developers in the United States. This rate is also lower than what top mobile developers with more extensive experience and a strong portfolio might charge.
