My background includes Linux and Windows administration, BIOS-level troubleshooting, bootloader recovery, OS deployment and migration, virtualization, database recovery, and remote technical support across Kali Linux, Fedora, Arch Linux, Debian-based distributions, Windows, and OpenCore macOS environments.
I strongly believe software should be secure, scalable, practical, maintainable, and understandable for the teams and businesses that depend on it. That philosophy guides how I build backend systems, design cloud infrastructure, and respond when production environments need immediate attention.
