❀️ Open-Source Philosophy

I strongly believe in the power of open-source software for learning, security, and innovation.

Why open-source?

  • πŸ” Transparency and trust
  • 🌍 Community-driven improvements
  • 🧠 Deep learning through customization
  • πŸ” Security through visibility, not obscurity

Most of my projects are built using open-source tools and platforms, and I enjoy contributing through documentation, testing, and sharing reproducible setups.


πŸ“˜ Documentation Standards

I believe clear documentation and open knowledge sharing are just as important as working systems.

Each project includes:

  • πŸ“„ Clear README with architecture overview
  • πŸ› οΈ Step-by-step setup instructions
  • πŸ” Security considerations
  • 🧠 What I learned & future improvements

All documentation is written with the mindset of open-source collaboration and reproducibility.
