Okay, let’s tackle this. So Keith has a mix of skills that are in demand, including technology transfer, software development, and quality systems. His experience in R&D and manufacturing adds to his value. Location is Grafton, MA, which is a smaller town, but still has a decent cost of living. Considering his skills, I'd estimate his hourly rate to be around $125, which is slightly below average for someone with his experience and skills in the US. This is because some of his skills, like technology transfer, might be more common in certain industries or companies, which could affect his earning potential. However, his experience in software development and quality systems keeps his rate relatively high.
