Being a senior developer is not just having a great skillset. You need to be able to manage your work in a way the business values it. You need to interact with all sorts of people in the company you work for and help other teammembers rwaching the same level as you.

Our senior developer is always thinking about the business value when estimates are made vs quality. He even does not do alot of softwae development, but is always asked to help out other developers, system engineers and even management to give advice.

To be able to do that in a professional way, your vision plus skillset makes you a senior imo. Not just the years of experience and amount of skills you have.
