Okay, let’s tackle this. So Francis has 8+ years of experience as a data scientist, which is a significant amount of time. He has a Master’s degree from Stanford University, which is a top-tier university. Location is San Francisco, California, which is a hub for tech companies and startups. Data scientists with his level of experience and education typically charge higher rates. Maybe around $150–$250 per hour? But considering his experience and education, maybe higher. Some top data scientists can charge $300–$500 per hour. Let’s check averages. Data scientists with his background might average $120–$200. So I’ll estimate around $125, which is on the lower end but still reflects his value.
