Since 2008, I have been running Składmuzyczny.pl, a music store in Krakow. This real business requires constant problem-solving — from customer service and marketing to building tools that support daily operations.
Every project I deliver sits at the intersection of technology, marketing, and organization. I don't build abstract solutions — each one addresses a specific problem and must deliver measurable results.
The motto of Skład Muzyczny is: "The Most Competent Music Store in Krakow". My philosophy is similar: there is nothing more practical than a good theory, because true competence begins where thought is born.
