In terms of Salary and Skills, it is not a dead-end. Salary will be raised as usual (depending on the company you are working for) and skills are constantly improving because every day you learn something and with new requirements, you will have to solve new challenges. In terms of job-role, it depends on you. You can become a Development Manager, Vice President and CTO (Chief Technology Officer). But if you don't want to get into Management and still be a Developer, you can do that too.
