Design and deployment of secure, self-hosted infrastructure for small teams and private communities. Core focus areas: • Ubuntu/Debian VPS hardening • WireGuard VPN deployment • Private voice server setup (Mumble) • Firewall and exposure reduction • Structured documentation and handover Work is delivered with clearly defined scope and controlled change processes, avoiding open-ended administration or undefined “security audits.” Projects typically involve securing newly provisioned VPS instances, replacing exposed SSH access with VPN-based administration, and implementing clean baseline configurations for long-term stability.
