Have you actually received offers at the junior/mid level? Or are you just thinking of applying?

I wouldn't worry about "years" too much. It's very very easy to work a number of years and still be a "junior" skill level. I see it all the time. It's not even a criticism of the person at all; if your job is "perform minor fixes/improvements to this web app" and you do that for 5 years, for example, you're not likely to have technical skills beyond the junior level even though you've worked for many years. This is not a problem. It just means that if you want to move your career forward you will need to find a position in a more tech-oriented, forward-moving, mentorship-based organization.

A senior developer at a non-tech organization can easily translate into a junior or mid level developer at a major tech or tech startup.
