Okay, let’s tackle this. So Jesse Collis has a strong skillset in iOS development, mobile applications, and PHP. His education from RMIT University is a plus. Location is Seattle, WA, which is a hub for tech companies. iOS developers with his level of expertise can charge around $100–$200 per hour. Considering his skills and location, I estimate his hourly rate to be around $125, which is slightly below the average for an iOS developer in the US. However, this is a rough estimate and may vary based on specific circumstances.
