Okay, let’s break it down. Matt has a mix of technical skills like iOS development, mobile product development, and software engineering, which are in demand. However, his skills are not extremely rare or unique. He also has some non-technical skills like public speaking and marketing, which are valuable but not as highly paid. Location is Seattle, which is a tech hub but not the most expensive market. Considering these factors, I estimate his hourly rate to be around $125, which is a reasonable rate for a software engineer with these skills in this location.
