Full-stack Compose Kotlin Multiplatform Masterclass

The Fullstack Compose Multiplatform Masterclass by Petros Efthymiou.

Learn how to build native iOS, Android, Desktop and Web apps with a single codebase.

- The sequel of the best-seller KMP Masterclass.

Are you following dozens of forums and articles and buying courses in order to move your development skills and career to the next level?

I am, too, but more often than not, after completing them, I realize that there is still a HUGE amount of work left to be done to connect all the pieces together and make them work on an actual production application. I found that even though a course was providing comprehensive knowledge on networking with Ktor, it didn't combine it with Clean architecture, dependency injection, or a local DB with SQL Delight. And because another course was extensive on SQL Delight, it was missing the rest of the best practises.

After buying courses, reading articles & forums, and getting my hands dirty, I combined the Compose Multiplatform best practices in a single course to build an actual production application together.

I created this course to make the process easier for you. You are going to learn how to combine:

Compose Multiplatform
Kotlin
Coroutines
Ktor
Koin
SQL Delight
Kotlin State Flow
Clean Architecture
MVI

And complete actual Android, iOS, Desktop and Web applications using the industry's best practices

My approach is to build an application together that can be forked and used as a base in your actual work.

Why Me?

I am a seasoned Mobile engineer, author, and Instructor with more than 10 years of experience. I have been working as a Mobile engineer from junior to lead positions in ambitious startups & large multinational companies since 2013. Being a sound engineer, though, doesn't automatically mean that you are an excellent instructor.

In my lifetime, I have trained hundreds of thousands of developers in classrooms, web conferences, video courses, blog posts, and books.

Among other things, I have created a best-selling Android Udemy course called Android TDD Masterclass. I have also written a best-selling Amazon book, Clean Mobile Architecture, which has prepared thousands of mobile developers to become mobile architects.

Furthermore, in the past 7 years, I have delivered countless courses, seminars, and lectures in institutions, including New York College and Hellenic American Union. My current position is as a Mobile Trainer in a Multinational company called Backbase, where I am training

Why is it important?

Kotlin Multiplatform is now considered stable and ready to be used in Android production applications. Compose Multiplatform is following the on the same successful path.

Unlike all other cross-platform applications with KMP you can rip the advantages of both native and cross-platform solutions. KMP gives you the option to build native UIs using Jetpack Compose and SwiftUI while sharing all the business logic, infrastructure, and boilerplate code.

On the other hand a startup the lacks the headcount and budget to hire specialized Android, iOS, web and potentially desktop devs can benefit greatly from Compose Multiplatform. Because you can build all those apps with a single codebase.

And unlike with all the other cross platform solutions you can still decide to build native UIs later one when the budget is secure, while getting to keep the biggest part of your codebase.

Currently Compose Multiplatform is a no-brainer compared to all the other cross-platform solutions.
