Okay, let’s calculate Maddy’s rate. She has experience in machine learning and data analysis, which are in-demand skills. However, her role and location are not specified. Assuming she’s a junior to mid-level software engineer in Aurora, IL, her rate might be lower than that of a senior engineer in a major city like New York or San Francisco. According to Glassdoor, the average software engineer salary in the Chicago area is around $110,000 per year. Considering Maddy’s skills and experience, I’d estimate her hourly rate to be around $120, which is roughly $25 per hour lower than the average. This is a reasonable estimate, given her location and level of experience.
