I harden enterprise infrastructure, identity systems, and networks to reduce operational risk.
PolandWhat I'm looking for
At CEVA Logistics, I secured and supported enterprise IT environments serving 1,000+ endpoints, leading vulnerability management, patching, VLAN segmentation, Network Access Control, and hardware-token MFA initiatives.
I built Python applications for logistics operations, migrated 32 TB of network shares to the cloud, virtualized critical Active Directory, DHCP, and DNS services, and introduced daily disaster-recovery snapshots. I also transitioned legacy productivity and ERP tools to SaaS across seven departments while reducing maintenance costs by 33%.
I've led IT teams, budgets, vendor relationships, compliance work, and project delivery, including GDPR/RODO controls that achieved 100% compliance in annual internal audits. I'm now building on my infrastructure background through cybersecurity and digital-forensics training, hands-on labs, and CISSP preparation.
