One option is to do become a freelancer.

Switching from being an employee to freelancing has increased my income by 2-3x.

The actual work is very similar to a day job and projects tend to be full-time and last long.

In case you don't have an own network, consider joining a recruitment freelance network. Then you can quit your job when you find a suitable project.

It might feel like a huge risk but in reality it is not that risky considering the high demand for developers. You can always go back to your job.

Of course difficult to say if that is a viable option to you but I would seriously consider it, at least research it further. Best of luck!
