Okay, let’s tackle this. So Bradley Johnson has skills in mobile applications, iOS development, and information security, which are in demand. He’s located in Seattle, which is a hub for tech companies. Based on national averages, iOS developers with similar skills can charge around $100–$150 per hour. However, considering his expertise in information security, which is a high-demand field, I’ll estimate his rate to be on the higher side. Maybe around $125 per hour, considering the cost of living in Seattle and the level of expertise he brings to the table.
