Okay, let’s tackle this. So Mark Martin has experience as a Java Software Engineer, which is a specialized role. According to national averages in the US, Java engineers with similar experience can charge between $80-$150 per hour. Considering Mark’s experience at Realdolmen, a reputable company, and his location in Miami, Florida, a major tech hub, I’ll estimate his hourly rate to be around $125, which is slightly below the national average but still reflective of his skills and experience.
