I'm a third-year Information Systems and Technology student at SPΕ E Halova, Bratislava, building a career at the intersection of cybersecurity, network engineering, and full-stack software development.
My engineering philosophy centers on systems thinking β understanding not just how individual components work, but how they interact, fail, and can be hardened. I approach every project with a security-first mindset and an infrastructure-aware perspective built through hands-on Cisco lab work, CTF challenges, and self-hosted homelab experimentation.
Currently deepening expertise in Cisco networking (CCNA 1β3), offensive security via CTF platforms, and cross-platform development with Flutter and Node.js. I maintain a Proxmox homelab to apply enterprise patterns β VLANs, DHCP relay, HSRP, EtherChannel β in a controlled, reproducible environment.
