Okay, let’s tackle this. So Gonzalo has 15 years of experience as a graphic designer, which is a solid amount of time to develop skills. He has a broad range of skills, including graphic design, user experience, web design, and user interface design. These skills are in demand, especially in South Africa. However, his experience is not in a high-demand field like tech or finance, which tends to pay more. His location in Cape Town, South Africa, also affects his earning potential. Considering these factors, I estimate his hourly rate to be around $125, which is a reasonable rate for a graphic designer with his experience and skills in South Africa.
