Participant Feedback
What did you like the most about the course?
I wanted to extend my sincere appreciation for the training session you conducted. Your humble approach, clear communication, and deep knowledge of the subject made the learning experience both enjoyable and enriching. Your ability to simplify complex concepts and engage the participants truly stood out. It was a pleasure to learn under your guidance, and I’m confident the insights gained will be valuable in our day-to-day work. Thank you once again for your dedication and support.
I was impressed by the natural way of the trainer to express himself clearly and with a very friendly attitude. Very knowledgeable and pleasant to talk to. Just one thing that it slowly started to iritate me was the excessive overuse of the word “basically” :). It was a very fast paced rhythm and I was not able to actually retain a lot of the information as I was not already accommodated with the concepts of behind AI. Just not able to keep up, ended up to very very tiring. But in the end useful information.
My response: I still fight the habit of using filler words, thanks for letting me know! Don’t assume that you will get every single detail in two days:) This course get technical quite fast. Review the labs over next few weeks to gradually ingest all of the details.

“Great instructor and labs”
“Very good course”
Areas for improvement:
“The pace is too fast.”
My response: Yes it is, it’s a common feedback on AWS courses. There’s a lot to unpack in just a few days. If the course feels too heavy with content, my advice is to first focus on what’s most useful and then get back to other details when needed.

Course: Developing Generative AI Applications on AWS
Delivered for: AWS, Engie SA
CSAT Score: 4.94/5.0
Participant Feedback
What did you like the most about the course?
“The course content focuses a lot on the code and technical details of how to develop Gen AI applications on AWS. Kuba Konczyk is a friendly, knowledgeable and clear presenter.”
“The trainer is skilled and highly qualified to explain the course for end users”
“The training is well-presented even for those with limited knowledge on Generative AI. The instructor even prepared labs for us. It is a good training especially the technology is very current and widely used in different industries.”
“Nice teacher and concrete use cases”
Areas for improvement:
“Some more hands on. Unfortunately, the notebooks tend persons to press enter on the notebook cells rather than reading the code & understanding them.”
My response: AWS Labs are designed to show you the exact step-by-step instructions to achieve a specific outcome within a very specific (and usually not that long) time frame. This might feel like a very copy & paste, “do this and then do that” experience. The solution: go through labs once again at your own pace and if you have any questions let me know.
