Okay, let’s break it down. Meiying has a broad range of skills, including software development, operating systems, and kernel programming. Her experience in Windows kernel programming and iOS development suggests she can command a high hourly rate. However, her location in Bellevue, Washington, is not in a top tech hub like San Francisco or New York. Considering her skills and experience, I estimate her hourly rate to be around $125, which is slightly lower than the national average for software developers in the US. This rate is also lower than what top tech talent in the region might command, but it's still a competitive rate for someone with her skillset and experience.
