Okay, let’s tackle this. So Dongping Luo has a Master’s degree in Computer Science and over 8 years of experience in software engineering, which is a solid foundation. He’s also located in Fremont, California, which is a hub for tech companies. His skills in cloud computing, big data, and data analytics are in demand. However, his rate is not too high because he doesn’t have any senior leadership or management experience. Based on national averages for software engineers in the US, his rate is around $120-$180 per hour. Considering his experience and location, I’ll estimate around $125 per hour.
