Okay, let’s break it down. Alex has a mix of technical skills like 3D rendering, Revit, and Sketchup, which are in demand. However, his role seems more focused on design and research rather than high-level architecture or engineering. Considering his location in Miami, where the design industry is relatively competitive, I'd estimate his hourly rate to be on the lower side. I'd compare this to junior designers or those with less experience in the area. A rough estimate for a designer with these skills in Miami would be around $75-$125 per hour. Let’s round down to $100.
