About Me
I am a mechatronics engineer bridging mechanical automotive design with modern software development. Professionally, I work as a mechanical design engineer specializing in hydrogen and electric city buses. In my free time, I build cross-platform mobile apps (such as Kids Safe Puzzles, DOPE Long Range Shooting Log) and data-intensive web platforms (CenyBroni.pl). I offer engineering consulting, parametric 3D CAD modeling, and custom software automation services.

BlogSport Shooting
In 2017, I discovered sport shooting. In 2018, I obtained my firearms license and started training and competing regularly. I am passionate about dynamic shooting (IPSC) — where speed, physical agility, and safe firearm handling under time pressure are key — as well as precision rifle and Long Range shooting. This passion also served as direct coding inspiration for the CenyBroni.pl price comparison platform and my DOPE Long Range Shooting Log mobile app.
