Hi, I'm Meryem Betül Çelik 👋

Computer Engineering Student · SOC / Security Operations · Offensive Security Background

🧭 About Me

I'm a Computer Engineering student focused on Security Operations (SOC) — log analysis, detection engineering, and incident triage. I started my cybersecurity path on the offensive side, and now I'm channeling that attacker mindset into building better detections.

  • 🔴 Started in cybersecurity on the offensive / red team side — Certified Associate Penetration Tester & Certified Web Security Expert (Hackviser)
  • 🔭 Currently building a SOC home lab: Splunk + Sysmon detection engineering against Caldera-simulated adversary techniques (MITRE ATT&CK)
  • 🌱 Bridging that red team background into blue team / detection engineering
  • 🎯 Open to opportunities in SOC / Security Operations
