You will only find out if you try it.

Even if you use Claude, as long as you know what you don't know, you can ask Claude to point you in the right direction.

You don't need a senior developer or permission to build.

PostgreSQL is a great database — I use it too, and I'd recommend it.

I wouldn't suggest Java though — it's too resource-heavy. If you have really good server resources, maybe consider it. But I'd recommend Rust instead. Don't be afraid — Claude will write most of the code for you. You just need to know how to debug.

As for Redis, you probably don't need it at the early stage. Only worry about it when your app has a lot of users — by then you'll naturally figure out how to use it.

One more thing: write detailed API documentation first. Everything should revolve around the docs. Don't rush into writing code. Trust me, documentation matters more than code.

Good luck, and go for it!

Admitting you can't design architecture shows real integrity that many wouldn't. But honestly, just go for it. Everyone learns from flaws.

PostgreSQL, Spring Boot, Angular, Python, and Redis are all popular choices, so Claude should be well enough versed to teach.

You don't have to go through books and documentation websites, and you'll lose the chance to learn if you try to one-shot it with Claude. It's good to start with a discussion, then build the spec, understand it, and go from there.

I think LLMs are never just vibing tools.
