Okay, let’s tackle this. So Ray Fortna has a strong background in Ruby, Ruby On Rails, and Agile Methodologies, which are in demand. He also has experience in scalability, distributed systems, and mobile applications. Location is Seattle, Washington, which is a hub for tech companies. According to Glassdoor, a software engineer in Seattle with similar skills can earn around $120-$180 per hour. Considering his skills and location, I estimate Ray could charge around $125 per hour, which is slightly below the average but still competitive.
