Reframe your stack.
You already think in objects, types, and the JVM. Learn Git, Python, TypeScript, Rust, and Node.js — each explained in the terms you already know, with a Java comparison in every lesson.
Modules
Node.js
Backend services, the event loop, and async — building a real API.
Git
Commits, branching, rebasing, and collaboration from the command line up.
Python
Dynamic typing, comprehensions, and a huge standard library.
TypeScript
Structural typing, generics, and inference.
Rust
Ownership, borrowing, traits, and fearless concurrency.
Microservices
Service boundaries, inter-service comms, resilience, and observability.
Every lesson speaks Java
Each concept is anchored to what you already know — Maven, Spring, the JVM — then extended into the new language or tool, with runnable exercises and a quiz to make it stick.
