RoR Dev & CTF Player

Hi, I am BarrYPL. I am currently working as a RoR Developer from KrakΓ³w, highly passionate about cybersecurity. For now, I am participating 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 can also take part in hardware CTFs. I like to share my knowledge with others, so I'll try to show you as much as I can on my blog. Here, you will find tutorials, insights, and my thoughts on the latest in cybersecurity. Feel free to check out my Github and some of the write-ups I have worked on.

Hope you'll enjoy it!
