Okay, let’s break it down. Daniel has a mix of technical skills, including signal processing, software defined radio, and wireless communications. These are specialized areas with a demand in industries like aerospace, defense, and telecommunications. His proficiency in programming languages like Python and C++ is also a plus. Considering his location in Alexandria, Virginia, which is a hub for defense and tech companies, I'd estimate his hourly rate to be around $125. This is slightly lower than the national average for engineers in these fields, but still competitive given his skills and location.
