Hi 👋 I'm Hyunbin

I'm a cybersecurity graduate currently working as an ICT Technician. I specialise in Linux systems, networking, and infrastructure security, applying a security-first mindset to enterprise IT environments.

My technical focus revolves around analysing systems from low-level components to backend services. I have a particular interest in routing behavior, packet-level debugging, and understanding real-world failure modes.

Most projects hosted here are infrastructure experiments and technical research.

🛠️ Technical Focus

  • Systems & Infrastructure: Linux internals, backend services, infrastructure debugging
  • Networking: Routing, NAT, packet-level analysis
  • Tooling: CLI development, backend automation

💻 Primary Languages

C / C++ • Java / Kotlin • Python • JavaScript • Bash • SQL
