“Mariusz has an aptitude for aesthetics and understanding clients that makes him stand out from the others. His designs are immersive and as one sinks into the detailed design study, one can never come out thinking of iteration. He pays attention to what you say during consultation sessions and tries to capture the essence of your requests in his designs. He doesn’t just create something that looks visually pleasing and engrossing, but he also makes sure that it reflects the values of your application be it web or mobile.”

“Mariusz zrealizował dla naszej firmy dwa ważne projekty. Mam nadzieję, że nie ostatnie. Współpraca układała się wzorowo. Przez cały czas mieliśmy świetny kontakt, który utrzymywał się nawet po zamknięciu projektów kiedy Mariusz (mimo, że nie musiał) sprawdzał jak wszystko wygląda na stronach docelowych. Wykonane prace były na wysokim poziomie.”
