About Cristian

Are you looking for someone who not only understands IT infrastructure but also implements it reliably?
I help companies design networks, server landscapes, and cloud systems to be secure, efficient, and future-proof.

With over 17 years of experience as an IT consultant, system administrator, and project manager, I offer practical solutions for:

Network design, firewall setups & VPN (Fortinet, Sophos)

Virtualization with VMware/Hyper-V

Migration to Microsoft 365 / Azure AD

Datacenter moves & backup strategies

Integration of CRM/ERP systems & inventory management

What makes me special? I speak not only "tech" but also "business": I explain complex topics understandably, think in processes – and work solution-oriented with all departments.

Whether it's data center modernization, cloud migration, site networking, or temporary project support – I deliver results you can rely on.

Let's make your IT more stable, secure, and future-proof together.
