Engineering as a lever for freedom. I build business tools and systems, taking full ownership of outcomes and ROI.
Designing scalable systems that align technical decisions with long-term business goals.
Designing solutions that help people complete tasks faster, with more confidence, and with less effort.
Transforming abstract technical requirements into tangible business value.

I have been programming for almost 10 years, and I can see how AI blurs the boundaries of seniority. Instead of an "I use AI" claim, I ran the MEGA Assessment from mega.dev: a measurement of 95 sessions and 172 real episodes of working with agents. It was a good decision.

For years I struggled with a qualified Certum signature on Linux. Turns out all it took was one missing driver and a pcscd service restart. Here is the story and the solution.
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.
