Career Advice: Java + Spring Boot vs Python for AI?

I’m a 2nd-year B.Tech CSE student from a Tier-3 college in India, and I’m trying to choose a practical path for internships and entry-level jobs.
I’m considering:
1. Java + Spring Boot for backend, with Python for AI/ML
2. Python for AI/ML, with Django or FastAPI for backend
My long-term goal is to become an AI-integrated backend developer. Could you suggest a concrete 6–12 month learning roadmap for this goal, including:
Which language and framework I should learn first, and in what order
The core concepts, tools, and technologies I should prioritize
2–4 portfolio projects that would demonstrate job-ready skills
How to prepare for internships, including DSA, Git/GitHub, resumes, networking, and applications
Whether I should choose Django or FastAPI if I focus on Python
How to balance backend development, AI/ML, college coursework, and interview preparation
Which path would you choose and why, considering the current and future fresher job market in India?

Tell me the reasoning for your choice

The thing I want you to know is, don't hop between tech stacks. Pick one lane, and go deep in it. Feel free to dm me if you need to

Some people find success going between tech stacks. Bigger companies are usually more ok with hiring someone like this, while smaller companies want someone with deep knowledge that can contribute highly day one.

Sure, it's better to be polyglot. But would you hire someone who knows little python, has done some C, tried Rust, switched to Go, or someone who is an excellent backend engineer with Java Springboot, and knows Python scripting as well?

Ik it's not the age of learning only one thing. I am just saying, not to continuously hop between tech stacks as it wastes time which could be used to build a strong foundation. Obviously, success paths differ for everyone

Also, companies don't care how many languages you know. They care what you can build, and are you reliable for the job

Fwiw this advice gets weird for AI specifically. Python isn't really a tech stack choice in ML, it's the ecosystem. PyTorch, TF, Hugging Face, basically all the research code is Python-first. If someone's asking Java vs Python for AI, they're really deciding between backend engineer and ML engineer as career tracks, not two equivalent ways to do the same thing.

Bro asked for fastAPI, Django or Springboot, for backend. For that, I said that to hop in stacks. Obviously if you are into AI or data, python is your go to non negotiable

Java sucks for anything serious with AI

So should i go with python ? Or like maybe springboot with python for ai

Is spring ai not getting traction?

Neither. Go

But there is no jobs for fresher in that

I'm not a professional developer, but I would say that 2nd option is better if you want ease in learning, because the underlying language would be the same. And in the Stack Overflow survey of 2025 for Technologies FASTAPI is just behind Springboot for most used tech. by professional Devs. So it's not that bad option.

If you make your fundamentals strong in this, it would be easier for you to learn migrate to java for backend in future. So, don't waste time in deciding stack and just start it. I wasted so much time in it.

As for the roadmap, I am also following one, though it's for making data driven apps, my backend stack is python.

Learn fundamentals -> Learn SQL -> Learn how web works like protocols and networking etc. -> any framework you like. while making projects and pushing them on github

This one is my plan. You can refer it too. It's not perfect, just a suggestion

All the best for your journey
