- Spanish Point Technologies
I liked how the course was structured. First day were basic definitions that I already knew but he clarified a lot of definitions that wasn't clear for me. The two following days I learnt some concepts that I didn't know and he explained them in an easy way to understand them.
Alicia Garcia Anton - Spanish Point Technologies
I liked learning about how Reactjs state management.
- Spanish Point Technologies
The example apps we built demonstrated the powers of React etc in a simple to understand way and will act as a good reference in future.
- UBS AG
I liked that after each part of theory, we got to try it out. I'm always better at learning by doing, so I thought it was very good. The trainer was very patient as well and made sure that everyone in the class understood the concepts and whenever someone struggled, he was more than happy to help. I thought the training was overall well balanced.

Skill level and rapor of trainer.
Louise Gilmore - AquaQ Analytics
Lukasz was very friendly and open, which made the training much more enjoyable. He did a good mix of lecture, examples and exercises. It was also good to ask us questions to test our understanding and correct if necessary. This was the main benefit of the training.
Luke Holmes - AquaQ Analytics
Good variations of the exercises available and provided after course.
- AquaQ Analytics
I was impressed with the facilities (web conference, remote desktops, resources) worked flawlessly. Nice not having to spend the first 10 minutes everyday getting things set up. I was also impressed with the amount of material that covered/presented/available. I was happy to see how comprehensive the course was.
- Stratasys
Łukasz was always trying to find a link to our company if he explained something, which is really helpful for us to understand it better. Łukasz is a trainer that will always do his best for the students and explain the same subject multiple times but still in a different way! Łukasz was also very flexible as a trainer and was always 'happy' and most important himself. We enjoyed the course very much with Łukasz.

Learning was comprehensive and catered to.
Wei Lin Tan - DBS Bank Limited
the triaing is good for fresher and it starts from the background and methodolegy level

The trainer tried to assess first the knowledge of his audience and based his classes from there. He even taught basic javascript to further understand once we go through the actual react framework.
DBS Bank Limited

DBS Bank Limited
The explanation to the concept is clear.
Noorazare Puasa - DBS Bank Limited
very hands on. trainer was very clear and knowledgavle
Li Fang Bren Ong - DBS Bank Limited
I really liked how Magesh took us through the fundamental problems that React and Redux solve, setting a good foundation and mental models for using the React ecosystem. The way he set up problems with initial naive implementations, then helped us to understand how to go about addressing those problems. I feel this is really important to help us avoid a lot of pitfalls that beginners can encounter. Magesh had good understanding of all of the tools we were learning, as well as some of the technologies we currently use outside of React/Redux - such as C#/.NET. He was able to compare/contrast the different paradigms between OO in C# and functional programming in React/Redux.

Getting to know more about React and TypeScript.

Great flexibility in learning areas. Nice, friendly atmopshere.
Mateusz Miazowski - GP Strategies Poland sp. z o.o.
Trainer patience. Trainer allowed to ask questions. Trainer during excercises asks activly if some help is needed and was very polite. Also at the points where all the group was not able to answer given by trainer question..trainer act very porffesionally explaining to as calmly sometimes some very basic concepts.
GP Strategies Poland sp. z o.o.
Luckasz is very happy and his mood his highly appreciated. He successfully helped us in any problem no matter how difficult they were. And lastly, he adapted the training to our requests, that shows a lot of flexibility and that is very good.

Kai Liknes - Arm
Remote learnig technology used + one month more access to the materials and trainer help!
Piotr Stefanski - Arm
How hands on it was! I have attended courses that are death by powerpoint, and at the end one is totally unable to do anything alone. But this was the exact opposite...exercises built on each other and were very practical. So I felt them relating to both the course, and potential outside uses. Kudos for the hands on aspect of the training!
Jordi Frances Matas - Arm
Day 2 was great with lots of coding.
