Server'larni boshqaraman,
tizimlarni qurib chiqaman.
Men Sanjar — Linux server administratori va infrastructure muhandisiman. Server konfiguratsiyasi, tarmoq xavfsizligi va avtomatlashtirish — mening asosiy yo'nalishlarim.
Nginx, Apache, Docker, Bash scripting, va Linux kernel bilan ishlash menga maroqli. Har bir server muammosi — bu yangi puzzle.
Mening maqsadim: tizimlar uptime 99.9% bilan ishlashi, xavfsizligi ta'minlangan va optimallashtirilgan bo'lishi.
