If you can accomplish what you want to build with frontend + firebase, then you've accomplished it! You can always fill out the backend skills later on. Firebase in particular is designed for rapid prototyping, "hackathon" style projects. With that said, building a toy API with authenticated data (user registration and the like) will help you understand the various ins and outs and will give you a better understanding of what services like Firebase offer and what their value is. Don't focus on premature optimization - by doing things in a naive way at first, you'll understand why various engineering practices became commonplace and you'll be able to more judiciously apply them instead of cargo culting. There's tons of ways to skin that cat, best thing to do is pick one and go for it.
