I just finished the **AI for Developers: From Assistant to Core** course by Valentine, and honestly… it was an amazing experience.
What stood out the most was how Valentine managed to **simplify complex ideas** in such a clear and approachable way. Concepts that initially felt intimidating suddenly started to make sense. The curriculum was incredibly well designed — it took us step by step from the basics all the way to more advanced topics in a very natural progression.
We started with the fundamentals (even “vibe coding”!) and gradually built our understanding until we were able to **build a voice assistant** by the end. That moment was a real *wow* for me — seeing everything come together after the journey through the course.
As a **product manager**, my goal wasn’t to become an AI engineer. I simply wanted to understand the key ideas behind what’s happening in AI today — not only in theory, but also in practice. This course delivered exactly that.
I’m leaving the course not only with new knowledge, but also with **much more confidence** when I look at the rapid developments in the AI space. It feels empowering to finally understand what’s going on under the hood.
Huge thanks to Valentine for such a thoughtful and engaging learning experience. Highly recommended.

I'm very grateful to Valentin and Olga for this course. It was wonderful!
I loved how hands-on it was — as hands-on as it gets. And I loved how both instructors handled questions. There was always a chance to talk to them directly at "office hours" meetings, and they gave tons of feedback on your work, which I think is even more valuable and rare.
What's important to understand about Valentin: he's not just someone who makes courses. He's sharing a live experience that he applies to building his own startup (one I'm sure we'll all know well soon enough). So this course is a real opportunity to tap into that experience firsthand.
Personally, I was an engineer and wrote a lot of code. But over the past couple of years, there just wasn't a need for it at work, so I stopped. This course — and the possibilities it showed me (writing apps and modules by voice? This still sounds crazy and cool at the same time!) — got me back into it. I'm writing — or, well, speaking? — code again now, and honestly, it feels like a lot of fun. That alone says a lot about the course.
It gives you information on the theoretical side as well, but the most important thing is the amount of direct, practical work. Everything is broken down through examples, and I think that's the only way people actually learn.
I also really appreciated how inclusive the course is. You can get real value out of it even if you're not an engineer or a technical person at all — you'll find your place here.
Thank you, Valentin and Olga. This was a great course.
