Okay, let’s tackle this. So Paulo has a strong set of skills in mobile app development, but he’s not a seasoned expert. He has some experience with languages like Java, JavaScript, and HTML 5, which are in demand. However, his lack of experience in other areas like backend development or full-stack development might bring his rate down. Considering his location in Spokane, Washington, which is not a major tech hub, I’d estimate his rate to be lower than what you’d see in Silicon Valley or New York. Average rates for junior mobile app developers in the US can range from $50 to $100 per hour. Given Paulo’s skills and experience, I’d estimate his rate to be around $75 per hour.
