On top of that, Rost’s experience in solution architecture really sets him apart. He knows how to design systems that not only work well now but also grow and adapt over time. He connects the technical side with the business side, making sure everything runs smoothly and efficiently.
But what really makes Rost valuable is his mindset. He doesn’t just fix problems — he helps shape the bigger picture. His ability to predict challenges and offer smart, practical solutions gives others the confidence to move forward without second-guessing.

I'm still new to the AWS world, but over the last few months, I have become much more confident in understanding when, why, and how to use different services and integrate them with each other. I want to give a big shout-out to Rost, who has been mentoring me during this time. He not only provided all the necessary resources and answered all my questions, but he also changed my approach to learning new things.

The most invaluable part of our sessions has been his experience with real production projects, where he shared how things truly work, which often didn't match what I saw in books or training sessions.

I want to say thank you, Rost, for all the time and energy you spent building my knowledge.
For those reading this comment later: if you have any plans to grow in technical aspects or soft skills, Rost definitely has something to offer, and I highly recommend not missing the opportunity to work with him. Best mentor ever!

His expertise and approach not only helped me feel more confident about my career goals but also equipped me with the right strategies to excel in my pursuit of a better job. I highly recommend consulting with Rostyslav for anyone seeking expert advice in these areas.
