About Me

Hello! I'm a Senior Systems Architect and DevOps Team Leader at Digi Romania (Backbone DevOps). With over two decades of experience in the IT industry, I specialize in building robust enterprise infrastructure, engineering custom network monitoring solutions, and driving full-stack automation.


Beyond traditional infrastructure, I'm the creator of the TankNote mobile app. My technical expertise spans across Linux systems engineering, Proxmox virtualization architectures, and advanced monitoring utilizing custom CheckMK graphs and time-series databases. Whether it's optimizing ISP-grade networks or designing modern data systems, I am passionate about creating efficient, scalable, and reliable technological foundations.
