I find Michal as a guy to whom you can apply for help in hopeless situations. I mean, he has an ability to solve unsolved or even insolvable issues. His analytical skills and pure, systematic, methodical, yet often unconventional, approach brings a remedy to the crisis. Even if he doesn’t know the solution to your problems at first you can be sure that he will do everything to find it and help you to understand how to avoid it in the future. He is an expert in areas of telecommunication but I think he would have been great in everything that needs logical thinking and finding solutions to unrevealed problems. With this comes an ease of spreading knowledge and willingness to share his expertise. He is a positive, proactive and perceptive fast learner striving to broaden his horizons which is combined with huge and broad knowledge and professional experience.

Michał is an open minded human being and when I think of him he is always that way. Regardless of obstacles he is always full of ideas and ALWAYS looking for company’s improvements mastering himself in the process. With a very strong can-do attitude, presenting out-of-the-box-thinking and readiness for sharing his enormous knowledge Michal is one the best employees I have had a pleasure to work with.
