Okay, let’s break this down. Matthew has a broad skill set, which is great, but it’s not extremely rare. He’s got experience in iOS development, which is in demand, but not as high as some other tech hubs. Location is Seattle, which is a mid-tier tech market. According to Glassdoor, average salaries for software developers in Seattle range from $100,000 to $160,000 per year. Considering this, and his skills, I’d estimate an hourly rate of around $120. This is slightly below the national average, but still a good starting point for a developer with his skills and experience.
