Okay, let’s tackle this. So Robert Williams has 24 years of experience as a software architect, which is a significant amount. His experience as Chief Software Architect at Auto Auction Services Corp. adds to his credibility. He also has a degree in Chemical Engineering from MIT, which is not directly related to software architecture but still indicates a strong educational background. Location is Tempe, Arizona, which is not a major tech hub but still has a decent cost of living. Considering his experience and education, I would estimate his hourly rate to be around $250, which is slightly below the average rate for a software architect in the US, but still competitive given his unique blend of technical and non-technical experience.
