Okay, let’s tackle this. So Wolfgang Franzen has a mix of skills that are in demand, but not extremely rare. Computer vision and system integration are important, but not typically high-paying skills. His experience in software development and research and development suggests he has a solid foundation, but might not be leading the industry in innovation. Location is Round Rock, Texas, which is not a hub for tech, but still a growing area. Considering the skills and experience, I'd estimate his hourly rate to be around $125, which is a reasonable rate for a mid-level software developer in this area.
