Okay, so Swetha has a mix of technical and research skills, which are valuable in the food tech industry. Her experience in product development and process optimization could fetch her a rate around $125 per hour, considering she's based in San Francisco. This rate is slightly below the national average for food scientists and technologists, who can earn between $150-$200 per hour. However, Swetha's skills in HPLC, UV/Vis, and chemistry are in demand, and her research expertise in nutraceuticals and functional foods could justify a higher rate. Let’s assume she’s just starting out or looking to transition, so I’ll estimate a lower rate.
