(づ◔ ͜ʖ◔)づ Johnathan's GitHubヽ(^ᴗ^ヽ)

Hi! (。^ ᴗ^)ノ I'm Johnathan, a passionate problem-solver, amateur music composer, and software engineer. I enjoy teaching others and thrive on learning new things. When not immersed in programming, I can be found taking walks, reflecting on life, and occasionally indulging in CTF challenges.

Lately, I've been diving deeper into penetration testing and working on a variations on a theme.

When it comes to personal preferences, I have an affinity for the sleek allure of dark mode. And yes, I must confess, I'm a fan of the controversial delightful combination of pineapple on pizza.

  • 🚀 I’m currently playing CTFs, tinkering with my blog, and composing variations on a theme.
  • 💬 Chat with me about programming (any language is fine!), software engineering, CTFs, music, audio engineering, writing, and life.
  • 📝 I write writeups, reflections, and tutorials.
  • ⚡ Fun fact: Did I mention I like dark mode and pineapple on pizza?
