I'm navigating the stack and going deep on cybersecurity. This blog is a running log of that: CTF and box walkthroughs, the tools I lean on, and notes I take along the way. A student breaking things to learn how to build them better.

What I work on

  • Penetration testing — web applications, network security, and infrastructure assessments.
  • CTF competitions — capture-the-flag events across a range of categories.
  • Bug bounty — hunting for vulnerabilities in real-world applications.
  • Security learning — new attack vectors and the defenses that answer them.

Skills

  • Web application security
  • Networks and systems
  • Reverse engineering
  • Scripting and coding
  • Linux system administration

Tools I reach for

  • Burp Suite, Nmap, Wireshark
  • Metasploit
  • Ghidra, Radare2

Same goes for security: learning by doing beats learning by reading.
