Okay, let’s tackle this. So Mario has a mix of technical and management skills, which is good. Electronics and automation are in demand, but not extremely so. He has experience in the automotive industry, which is a niche. Project management skills are also valuable. Considering his skills and location in Royal Oak, Michigan, I’d estimate his rate to be on the lower side of the scale. Maybe around $75 per hour, which is a reasonable rate for an entry-level or mid-level engineer in this field, especially in the Midwest.
