Self-Study | Independent Learning Path
Home February, 2025 - Present

Self-study in cybersecurity and IT

Beyond formal coursework I pursue self-directed study in software development, cybersecurity, and systems engineering—reinforcing theory with hands-on labs.

Key self-study projects ▾
  • Set up home labs for networking, system administration, and ethical hacking.
  • Building proficiency with RustDesk, Docker, Visual Studio Code, and WSL.
  • Deploying Ubuntu & Kali Linux and experimenting with Kali KeX GUI for penetration testing.
  • Exploring secure deployment on local servers and cloud platforms such as Linode.
  • Coding in Java and creating automation scripts for cybersecurity tasks.

This self-driven approach solidifies classroom knowledge with real-world experience and keeps me progressing toward certification readiness.
