Bite-Sized Chunks

Suggested Paths

For beginners, the biggest risk isn't picking the "wrong" topic — it's overwhelm and quitting. Pick a goal, follow the order. Each track starts from a shared Python + CS + Math foundation.

Everyone starts here

Foundation · ~3 months part-time

Everyone starts here. Python builds confidence fast because you see results immediately; CS gives you the vocabulary every other course assumes; Math is a slow background drip — not a blocker.

  1. 1

    Python

    Programming Languages · Beginner · 1,289 lessons

    First language. Quick wins build the habit before anything harder.

    Start course →

  2. 2

    Computer Science

    Foundations · Intermediate · 2,872 lessons

    Light pass — variables, functions, data structures, complexity. The vocabulary downstream courses assume.

    Start course →

  3. 3

    Mathematics

    Foundations · Beginner · 3,121 lessons

    Background drip: discrete logic, basic stats, a touch of linear algebra. Don't wait to finish before moving on.

Backend / Infrastructure

~9–12 months part-time after foundation

The 'boring' early path that produces engineers who get hired into senior roles fastest. Delayed reward, but real.

Log in to save this path to your profile and track progress.

  1. 1

    Software Engineering

    Software Engineering · Intermediate · 1,933 lessons

    Version control, testing, code review — the habits that separate junior from senior.

    Start course →

  2. 2

    Java

    Programming Languages · Intermediate · 2,870 lessons

    A workhorse backend language. Strong typing, mature ecosystem, and the lingua franca of large-scale server systems.

  3. 3

    System Design

    Software Engineering · Advanced · 1,919 lessons

    Architect scalable, reliable distributed systems. The senior-engineer toolkit.

  4. 4

    Cloud and Infrastructure

    Infrastructure & Security · Intermediate · 2,989 lessons

    AWS/GCP/Azure, containers, infrastructure as code. Where backends actually run.

    Start course →

  5. 5

    Security

    Infrastructure & Security · Intermediate · 3,052 lessons

    Threat models, cryptography, defensive engineering. Know this before going to production.

Beginner-protection rules

Apply these regardless of which track you pick.

  • Don't wait to finish Math before moving on — keep it as a background track.
  • Ship one real app before circling back to Security and System Design.
  • Don't rush ML/DL — without stats, you'll run libraries you can't reason about.
  • Pick one language at a time. Switching too early kills momentum.
  • Pick a track and commit for at least a month before second-guessing it. Overwhelm and quitting are the real risks — not picking the 'wrong' path.
