The idea behind the work

Building things, breaking things, learning how they work. πŸ’»πŸ”

I'm a Romanian high school student specializing in Mathematics and Informatics, with bilingual English education. I enjoy solving complex problems, exploring technical systems, and turning what I learn into practical projects.

My interests span computer networks, cybersecurity, software engineering, and the intersection between systems and security. I learn best by experimenting, building, troubleshooting, and documenting the process.
