Okay, let’s calculate this. So Mehmet has 30+ years of experience in mechanical engineering, which is a significant amount of time. He has held senior roles at Polinas Plastics and Vestel, which suggests he has strong industry connections and expertise. However, his role is in predictive maintenance and quality assurance, which might not be as high-demand as other fields like software development or finance. Considering his location in Manisa, Türkiye, and his industry experience, I would estimate his hourly rate to be around $125. This is slightly lower than the average rate for mechanical engineers in the US, but taking into account the regional difference and his specific role, it seems reasonable.
