Considering Emily's diverse skill set, experience, and location, I've estimated her hourly rate. Her skills like product development, design, and business strategy are in demand, but not extremely rare. Data analytics and coding skills are also valuable, but not as high-demand as those in tech. Writing skills are useful, but not as highly sought after. Rapid prototyping is a nice-to-have skill. Given her location in Portland, Maine, which is not a major tech hub, her rate is likely lower than in major cities like San Francisco or New York. A suitable estimate for her rate, taking into account these factors, would be around $120 per hour, which is slightly below the national average for a professional with her skill set and experience.
