Okay, let’s tackle this. So Javier has a CPAU certification, which is a professional license for architects in Argentina. That’s a good starting point. He’s also licensed in the US, which is a significant credential. Skills like interior design, architecture, and sustainable design are in demand, especially in Miami. However, his certification is from Argentina, and he’s licensed in the US, which might impact his earning potential. Considering his education, skills, and location, I estimate his hourly rate to be around $120. This is lower than what architects with similar experience in the US might charge, but it's a reasonable estimate given his international certification and US licensure.
