Okay, let’s tackle this. So Sion Kidane has 33 years of experience as a transportation engineer and project manager, which is extremely valuable. He has worked for CALTRANS, a major transportation agency in California. This experience, combined with his education from the University of California, Berkeley, suggests that he is a highly skilled professional. His skills in civil engineering, project management, and strategic planning are in high demand. Given his level of experience and expertise, I would estimate his hourly rate to be around $250. This is slightly lower than what I would expect for a senior-level civil engineer with similar experience, but it's still a very competitive rate for someone with his background and experience in the Bay Area.
