Is this course for you?

If this sounds familiar... This course is or you!

You use Jetpack Compose in real projects

You struggle with architecture and state complexity

You want predictable, scalable UI code

You care about long-term maintainability, not just “making it work”

What will you learn

What will you gain?

01.
Solid mental models for state, side-effects, and recomposition; how to diagnose and prevent laggy UI.
02.
How modifiers work, and how their order affects UI; when to write custom modifiers and how to implement them correctly.
03.
Patterns for navigation and state hoisting that scale across the whole application.
04.
Reliable Compose UI testing: semantics, idling, and screenshot testing to catch regressions.
05.
Perils and pitfalls of the most common architectural patterns: MVVM, UiState, UiAction.
06.
Best practices, everyday use cases, and mistakes to avoid in Compose projects.

Feedback

Real feedback from engineers mastering Kotlin Coroutines.

I really loved the exercises. They felt like taken from real life projects and very organic. The automated tests with the additional feedback had a great effect on my learning.

Matthias
Full Stack Developer & Project Lead

Thanks to the course, I realized the subtlety of using co-programs in Kotlin, received good mentoring from teachers. The consistent structure of explaining topics always keeps the focus, smoothly leading to tasks that allow you to realize the acquired skills.

Shamil Gulmetov
Android Developer

The material is thorough and clearly explained, though intellectually demanding and requiring real time investment. The foundations are solid, but you still need your own practice to solidify the knowledge.

Artur Wronski
Backend Developer

The course was well-structured to me, with all information presented clearly. The exercises were interesting and feedback was quick and constructive. The Q&As with JetBrains members were a great addition, thank you!

Max Shchezhin
Android Developer

The course is well-paced, the exercises are appropriate and Marcin made sure to answer all questions. By far one of the best software courses I've taken.

Nacho
Software Engineer

Marcin made this knowledge easy to learn and practice, what saves us a lot of time.

Krystian Mateja
Senior Engineer

I like that we have 6 months to finish all tasks and the project because most of us don't get to listen to the course every day.


I still have some uncertanties, but am much more confident in what I do and I'm still referencing the course materials which are very helpful for quick reminder of what to do.
