About

Eğitim hayatım boyunca bilişim alanında ilerledim. Profesyonel kariyerime destek uzmanı olarak başladım ve bugün; Windows Server rolleri, Microsoft 365 / Office 365, VMware, Veeam, Zerto, fiziksel sunucu ve storage altyapılarının kurulum, yapılandırma, yönetim ve sürekliliğinde aktif rol alan bir Sistem Mühendisi olarak kariyerime devam ediyorum. Kariyerime işin mutfağından başlamış olmam, hem saha operasyonlarını hem de merkezi sistem mimarisini iyi tanımamı sağladı. Bu sayede karşılaşılan problemleri yalnızca yazılımsal veya donanımsal başlıklar altında değil; uçtan uca, mimari bir bütünlük içinde değerlendirme ve kalıcı çözümler üretme alışkanlığına sahibim. Yer aldığım çalışmalarda, yalnızca mevcut sistemlerin işletilmesine değil; yüksek erişilebilirlik, veri güvenliği ve felaket kurtarma odaklı altyapıların tasarlanmasına ve iyileştirilmesine katkı sağlamayı hedeflerim. Projelere görev bazlı değil, değer katan ve sürdürülebilir çözümler üretme bakış açısıyla yaklaşırım. Değişen teknolojileri ve sektör dinamiklerini yakından takip ederek bilgi birikimimi sürekli güncel tutmaya özen gösteriyorum. Aynı zamanda yer aldığım projeleri, yalnızca birer iş kalemi değil; uzmanlık seviyemi derinleştirmek, teknik yetkinliğimi artırmak ve mimari bakış açımı geliştirmek için fırsatlar olarak görüyorum.
