Okay, let’s calculate this. Edmund has a solid set of skills, including JavaScript, Node.js, and databases. He’s also familiar with Express, React, and Git. However, his experience is not as extensive as some other developers, and he lacks experience with Angularjs. Considering his skills and location in San Francisco, I’m estimating his hourly rate to be around $125. This is slightly below average for a full-stack developer in this location, but his skillset is not overly specialized, which keeps the rate in check. Some full-stack developers in San Francisco can charge upwards of $200 per hour, but Edmund’s skills don’t quite align with the highest demand. This rate is more in line with what you might expect for a junior or mid-level full-stack developer in this location.
