The cost of a full-stack developer depends on the type of work you need to be done, the experience level of the developer, and how much time they're willing to spend on your project.
As per Indeed, $35.47 per hour is feasible for a newbie or one who has only worked on small projects. If you're looking for someone who can do more complex work, like building a larger application or working on large databases, the cost can go up to $45.2 per hour.
For developers who have years of experience in their field and are highly skilled, the cost range varies between $55-$75 per hour.
