I didn't even get really good until I was in my early 30s, after 20 years of coding. The fact that you've been coding already means that - if you keep the humble attitude and keep learning - you'll have no problem.

The ability to learn and adapt - to be able to dig into problems and understand them, filling knowledge gaps as you go - is what you need to be a good engineer. Looks like you have that.
