Unity Developer | Wroclaw, Poland
Greetings!
Graduate of Creative Media & Game Technologies. I love building playful, performant interactive experiences and polished tools.
About me
I'm a Unity developer based in Wroclaw, Poland, with a passion for creating and experimenting. I enjoy building games and tools from scratch, exploring new ideas, and improving the things I use every day.
Outside of work, I'm into gaming and custom keyboards - I like tinkering with hardware and trying out new setups just to see what's possible.
Featured: Mindful Focus
Open page
Mindful Focus is a small project I have been working on that helps with addressing your internal state whilst you find yourself getting distracted.
Being able to write down what it is that causes your distraction personally helped me to get back on track with more clarity.
Making this extension was a way for me to catch myself immediately when opening a distracting webpage instead of having to do it manually and writing it down with pen and paper.
