Thanks a lot Jakub,
I understand now so much about structuring my React app with
REDUX.
Your work is very well organized and your explanations are clear as water.
See you next time, with pleasure !!!

Jakub is a great mentor for people of all levels. He's able to easily understand where your proficient and fill in the gaps in an easy-to-understand manner. I personally, liked how he was very mindful of my time and didn't skimp around with long explanations - everything was clear and to the point.
He was able to teach me something new, fix my code, and empower me for future problems. Truly great.
