All writeups

Welcome to my writeups

  • intro

Hi, I’m Viktor. I currently work in QA — testing web, mobile and AI apps, finding the edge cases nobody thought about, and breaking things before users do. In my free time I dig into cybersecurity, which I believe will matter more than ever as AI becomes part of everything we build.

Why writeups

Writing things down is the best way I know to actually understand them. Every writeup here is a note to my future self that might also be useful to you: what I tried, what worked, what didn’t, and what I learned along the way.

What you’ll find here

  • Web, mobile & AI apps — findings, testing approaches and the tools behind them.
  • Labs & CTFs — walkthroughs of the challenges and practice environments I work through.
  • My journey from QA into security — what carries over from testing, what doesn’t, and what I’m learning along the way.
