Bartosz Osuch
RoR Dev & CTF Player
Hi, I am BarrYPL. I work as a penetration tester based in Kraków, coming from a background in Ruby on Rails development. I compete in CTFs as a member of the Polish team Mindcrafters.
My favorite categories are Websec, Crypto, and PWN. Since I previously worked as an electrical engineer in R&D, I also take part in hardware CTFs.
I like sharing what I learn, so check out my blog for tutorials, insights, and write-ups on the latest in cybersecurity, as well as my GitHub.
Hope you'll enjoy it!
