Okay, let’s break it down. Jeff has 34 years of experience in automotive and supply chain management, which is a significant amount of time. His skills in Lean Manufacturing, Six Sigma, and Process Engineering are in demand across various industries. However, his experience is mostly in the automotive sector, which might limit his earning potential. Location is McAllen, Texas, which is not a major hub for these types of professionals. Considering his experience, skills, and location, I estimate his hourly rate to be around $125, which is below average for someone with his experience and skills in the United States.
