Stable infrastructure. Security by design.
I design, secure and maintain IT environments—from networks, firewalls and Linux systems to monitoring, Smart Home and SATEL alarm systems.
01 / Services
One system, from network packet to application.
Networks & security
LAN/WAN, segmentation, Wi-Fi, firewalls, OPNsense, VPN, DNS/DHCP, TLS, WAF and controlled service exposure.
Smart Home & SATEL
Scope design, integration, configuration and diagnostics, including secure IoT networking.
02 / Approach
Evidence before assumptions.
Diagnosis based on logs and metrics, a controlled implementation with rollback planning, and validation through monitoring. Work can be performed remotely or on-site depending on its scope.
