Okay, let’s calculate this. So Sandhya has 12 years of experience as a software engineer, which is a solid amount of time. Location is Chennai, India, which is a growing tech hub. The industry average for software engineers in India is around $25-$50 per hour, considering the cost of living. However, this person has a degree in Physics, which is not directly related to software engineering. This might impact her earning potential. Let’s assume she’s a general software engineer, not specializing in a specific area. Based on industry averages and considering her experience, I’d estimate her hourly rate to be around $75, which is on the lower end of the scale.
