About

Final-year software-engineering student turned junior penetration tester.

I’m Baha — a final-year software-engineering student in İstanbul who wandered into offensive security and never looked back. What started as curiosity about how systems break turned into the work I want to do for a living: finding the flaw before someone with worse intentions does.

Day to day I break web, network and AI/ML targets on TryHackMe and Hack The Box. I build my own tooling instead of leaning on someone else’s black box, and I document every step — recon, foothold, privilege escalation — so a finding can be reproduced, not just claimed.

Right now I’m grinding toward the OSCP and looking for a junior penetration tester role — based in Türkiye or fully remote. I’m early in the journey and honest about it, but I learn fast, write things down, and show up hungry.
