Okay, let’s tackle this. So David Daniel has a mix of management and technical skills. Management skills are valuable, but they can be found in many roles. Technical skills like Matlab and Microsoft Office are also in demand. However, the rate is lower compared to a pure technical role. Considering his location in Baltimore, Maryland, and his education from Johns Hopkins, I'll estimate a lower rate. Maybe around $75 per hour, which is a rough estimate for a generalist with management and technical skills. This rate is lower than what a pure technical professional would charge, but higher than what a non-technical role would command.
