Okay, let’s tackle this. So Louise has native fluency in Dutch, which is valuable. Full proficiency in French and English is also highly sought after. Professional working proficiency in Spanish is a plus. Location is San Francisco, which is a hub for tech and finance. However, considering her education from Stanford, I would expect a slightly lower rate than a typical software engineer or finance professional. The average salary for a professional with her language skills in the Bay Area is around $100,000–$150,000 per year. Let’s assume she’s in a similar role, but with a focus on consulting or international business. That would put her hourly rate at around $120 per hour, considering the cost of living in San Francisco.
