Explore Roadmap

Do I need prior programming experience?

Not at all! The Foundation track is designed for absolute beginners. We start from basic concepts and build up gradually.

How long does it take to complete the roadmap?

At 5-6 hours per week, you can complete the full curriculum in about 4 months. The material is entirely self-paced and free to read anytime.

Is this a coding bootcamp?

No. We focus on deep fundamental understanding rather than rushing to build specific apps. You'll learn to think like an engineer.

Is Byteion free?

Yes! Byteion Academy is completely free and open. We believe foundational education should be accessible to everyone.
