I found the course very useful and productive. Antonio and Nino have really put in the work to make sure it is so.

The truth is that I had some experience with prompts and Claude Code, but I needed to enrich it with the basic fundamentals, MCPs, skills, and the different methodologies that are emerging to accelerate and improve the results obtained by the agents. Without a doubt, very useful to get up to date, improve skills, and stay informed without having to search for information in countless sources.

The training has been extremely valuable, the knowledge that has been shared and the way it was delivered truly meant a total change in the paradigm I had.

Although I already had some experience using AI tools, I wasn't entirely sure how to use them correctly to avoid falling into Vibe Coding directly and to achieve proper orchestration of the tools.

The course has been impressive for several reasons.

The order of the lessons seems very appropriate to me, allowing you to go from less to more, the quality of the classes has been very good, with unbeatable treatment, and moreover, they have managed to cover a lot of information in a very short time.

I would also like to point out how quickly they have adapted the content as things changed, which in this sector is every 10 minutes.

I have taken several courses taught by Antonio, and all of them have met my expectations.

From my point of view, the strongest aspects are that the content is very well explained, structured, updated quite regularly, and there is a balance between theory and practice.

It is also very interesting that you have access to the course content once you have finished them.

Kotlin Expert, Jetpack Compose

★★★★★
The course "Kotlin Expert and Jetpack Compose" by Antonio Leiva has been a transformative experience for me as an Android developer. Antonio explains advanced Kotlin topics, such as coroutines and functional programming, with clarity and depth, while the practical approach to Jetpack Compose allowed me to master this new declarative design paradigm. In addition, the real-world examples and practical exercises make the learning highly applicable to daily work. The active community and Q&A sessions with Antonio are a huge added value, as you always have support to resolve doubts. Overall, it is an excellent course that I recommend to any developer who wants to take their skills to the next level.

In a short time, you can get up to speed with the best practices in Android testing, guided step by step by Antonio.

I recommend it, even if you have already worked with unit tests. The UI testing module is very interesting.

The course is well structured and is aimed at building code as the concepts are explained.

It’s true that the pace of technology updates hasn’t been fully reflected in this current version of the course, so sometimes applying certain dependencies (and the appearance of the Kotlin 2.0 compiler) creates learning bottlenecks that, since it’s a non-tutored course, cause slowdowns when trying to put everything taught into practice.

First of all, congratulations on the course!
I really liked the first part, which dealt with the technical topics of the language itself, although I have to say I missed more examples and more details on usage.
Regarding the second part, the multiplatform one, I found it very difficult to follow Antonio at every step, since Android Studio + IntelliJ IDEA have changed versions and many options shown no longer exist or the creation flow has changed. In fact, I think it’s a good time to update the content, maybe using Fleet directly. That way, the part about refactoring the project and moving things around might be much less confusing.

Thank you!

I’d like to highlight that there are many trainings that don’t cover certain aspects that are explained here, and the Multiplatform part is still very little covered by trainings.

It covers many topics that may be needed on a daily basis, and the way concepts are explained makes it very manageable and easy. If I had to mention a downside, which it really doesn't need, I would say it would be interesting to cover Jetpack Compose for TV, Car, or Wear OS in some module.

General opinion: I loved this journey through everything you can do with Kotlin and diving deep into many aspects of the language.

What I liked most: Being able to create a backend with Kotlin... this part felt a bit short to me. I would have liked to see how to connect to an external database and a bit about tools that can be used for better code or security.

Thank you very much Antonio for the effort you are making for the community.

Additionally, I would like to highlight that the inclusion of content on Compose and Kotlin Multiplatform in the training has been a great added value. Compose is a very relevant technology nowadays, and teaching Kotlin Multiplatform opens up a world of possibilities for developing applications on different platforms efficiently.

Dear team,

Thank you very much for this training. I enjoyed every step. I would have liked it to be completed in less time, since it was a gamble to join this training when it wasn't finished. This delay meant I didn't join other trainings until this one was done. I was afraid it wouldn't be completed. Luckily, I was wrong.

On the other hand, I think all the sections related to the language were very valuable and, humbly, I think it could be a training on its own.

Now that the training is finished, I will very likely join the Compose training.

Best regards and until next time

Also, having the possibility to clear up doubts is priceless, especially with Spanish-speaking experts who know the subject. More than recommended, this training is worth every peso.

A good course, I mainly come from C++ and I have a clear understanding of OOP concepts. I had to review Java since the course
almost constantly highlights the advantages of Kotlin over Java, which you can't appreciate if you don't know at least a little Java, which is even assumed in some modules of the book. But the reality is that knowing almost nothing about Java when I started the course, now I can handle both languages. One more step towards my goal, which is to sell freelance Android services and make a living from it.

This training has exceeded my expectations, the investment was worth it. Antonio explains complex topics with an ease that many courses don't achieve so easily.

And another thing I like about him as a teacher is that, when developing a topic in code, he explains the reasoning behind what you're writing at a depth that's also uncommon to find in many online courses, whether free or paid.

Really, 100% recommended course.

The course is splendid, the way the topics are explained and how the practice is carried out is truly incredible.

I've been using Java for a long time, and with the syllabus and pace of this course, it's really very good. Everything is made clear and you can start developing in Kotlin right away.

Here I truly discovered the magic of Kotlin.

I had taken some courses on Kotlin before, but in this training I learned about many tools that hadn't even been mentioned in the other courses.

I think, as Antonio says, here I truly discovered the magic of Kotlin: many tools to put into practice to reduce code, make it more readable and simplified.
