Okay, let’s tackle this. So Phillip Erwin has a broad range of skills, including aerospace, embedded systems, and program management. His programming skills in C, C++, and Fortran are also valuable. However, the market demand for these skills can vary. Considering his location in San Dimas, California, which is near Los Angeles, I'd look at average salaries for similar professionals in the area. According to data, aerospace engineers and embedded systems specialists can earn around $120,000-$180,000 per year. Program managers in this field can earn around $100,000-$150,000 per year. Taking into account his skills and experience, I'd estimate his hourly rate to be around $125, which is on the lower end of the range but still reasonable considering his location and the current market demand.
