04 / Beyond the screen

An engineer.
And a little more.

Quality engineering is where I bring my skills together: a testing mindset, backend development experience, and confidence working with AI. I enjoy understanding how systems behave and finding ways to make them more reliable. I value teams that communicate openly and keep learning.

Away from the keyboard, you’ll find me playing guitar or singing with TS Samo Tvoji ↗. Football, street workout, and boxing keep me moving.
