Okay, let’s calculate Don’s rate. So, with 15+ years of experience in software development and IT management, Don is a seasoned professional. His education from the University of California, Santa Barbara, adds value. Location is Carpinteria, California, which is a desirable area for IT professionals. Considering the national average for software developers and IT managers, I estimate Don’s rate to be around $125 per hour, which is slightly lower than the national average due to his location. However, this is still a competitive rate for his skills and experience.
