Based on the provided skills and experience, I estimate Fasheng Li's hourly rate to be around $125. This is a relatively conservative estimate, considering the demand for skilled software developers in Seattle. The average hourly rate for a software developer in the US can range from $100 to $200 per hour, depending on the location, industry, and level of experience. Fasheng's working proficiency in English and native proficiency in Chinese may also impact his earning potential. However, without additional information on his experience and qualifications, I've kept the estimate relatively low. As a rough estimate, I've considered the following: Ruby developers in the US can earn around $100-$150 per hour, while more experienced developers can earn up to $200 per hour. Given Fasheng's skills and experience, I've placed him in the lower to middle range of this spectrum.
