Introduction
Hi, I’m Nitel 👋 Application Security & Penetration Testing Specialist based in Seoul, South Korea.
I write about offensive security, penetration testing, and the intersection of secure development — from breaking things in labs to building them the right way in production.
What I Do I’m an offensive security professional with a background in full-stack development (React.js / Node.js). I hold the HTB Certified Penetration Testing Specialist (CPTS) and PJPT certifications, and I’m currently pursuing OSCP.
