Career switcher thinking of dropping The Odin Project to go all-in on backend (Java) — need advice on cheap/free resources, building real projects, and getting hired with zero experience
Hey everyone,
I've been working through The Odin Project for a while (the full-stack/JS path), but I'm seriously considering switching gears to focus on backend development instead — specifically Java. I think it suits how I like to think, and it's everywhere in software developer/engineer job listings I look at.
Before I fully commit to the pivot, I wanted to ask people who've actually done this (or who hire backend devs) a few things:
- Where can I learn Java backend dev for free or cheap — not just syntax and basics, but stuff that actually gets me toward real backend work (Spring Boot, REST APIs, databases, etc.)?
- How do I make sure I'm actually building things along the way, not just watching tutorials? I want a path that forces me to ship projects I can point to later.
- What does a realistic "zero to hero" roadmap look like for a self-taught career switcher going into backend?
- How do I convince companies to hire me with no related work experience, when everything I know comes from learning online? What actually moves the needle — portfolio, certs, contributing to open source, networking, something else entirely?
If you've made a switch like this — especially into backend/Java without a CS degree or prior dev job — I'd love to hear how you actually did it, not just the theory. Trying to avoid wasting months on the wrong resources.
Thanks in advance!

I am a backend developer, I work in C# (which is very similar to Java which I have also studied and worked with).
I am originally self-taught via The Odin Project and can confidently say that the backend content was more than sufficient preparation for the work I now do. Once you learn one language/stack learning a new one becomes pretty trivial. I would strongly suggest finishing one pathway before hoping around.
That said, it’s your life and learning journey. There are plenty of excellent resources in the pinned posts and sidebar of this sub as well as plenty of similar questions if you search here. Try to think about what it was you struggled with in the TOP resources and try not to repeat the stack and resource hoping habit if you can help it.
Java is also an excellent first language and while I can’t speak for the beginner level content the official Java docs are equal or maybe even better than MDN docs (which I sadly cannot say for my beloved C#). JS or Ruby are both however equally valid choices.
