Hello friends,
It's been 1 year I'm working as FrontEnd Developer in a startup, have a good working experience on working tools/framework like React, Redux, saga, styled components, ramda etc.

Now when I see job posting regarding a Senior frontend developer role, most of requirements they want I have experience with.

So can I apply for Senior Developer position?

Is there a rule of thumb that I can know I'm ready to apply for senior Developer position?
