Based on the provided information, I estimated Mihai's hourly rate to be around $120. This is a relatively conservative estimate considering his skills in multiple programming languages and technologies. However, without specific experience in high-demand areas like cloud computing or artificial intelligence, the rate is on the lower side. Average rates for software developers in Seattle, Washington, range from $100 to $200 per hour, depending on the specific skills and experience. Given Mihai's unique blend of technical and practical skills, he may be able to command a higher rate, potentially upwards of $180 per hour.
