Why This Site Exists

After five years in IT support, witnessing a ransomware incident firsthand pushed me toward prevention instead of cleanup. I created CybersecurityJunior to:

  1. Hold myself accountable by shipping public work and documenting progress
  2. Share working code, not just talking points—everything here is battle-tested
  3. Help other career-transitioners by showing the unpolished, real path to cybersecurity
  4. Build in public to prove that unconventional backgrounds can thrive in security through relentless practice
