Okay, let’s tackle this. So Evan Kerr has an extremely long experience of 42 years in electrical design, system engineering, and module design. This is unusually long for an engineer, especially in a field like electrical design. Considering his experience, location (Cape Town, South Africa), and industry (energy sector), his rate would likely be on the lower side compared to what I’d expect in the US or Europe. However, his experience is so extensive that he might be able to negotiate a higher rate. Let’s assume a rate of $150 per hour, which is relatively low considering his experience. This rate is more in line with what I’d expect for a senior engineer in a large organization in South Africa.
