Okay, let’s tackle this. So Vance has a strong skill set in software design, operating systems, and mobile app dev. He’s also proficient in C++ and Agile methodologies. Location is Seattle, which is a hub for tech companies. Average software engineer rates in Seattle are around $120–$180 per hour. Considering his skills and experience, I’d estimate his rate to be on the lower end of that range, around $125 per hour. Some junior software engineers in the area might charge lower, but Vance’s expertise and experience suggest he could command a higher rate. Maybe $150–$200 per hour, but based on the data, I’m sticking with $125.
