Hire the Best Linux System Administrators
in Italy

The SysAdmin Who Fixes What He Audits Your infrastructure is critical. Whether it's a server down at 3 AM, a DevOps pipeline that needs to be bulletproofed, or a NIS2 compliance deadline three weeks away — you need someone who understands both the code and the consequences. I'm Giuseppe. 12+ years managing production Linux infrastructure for hosting providers, SaaS platforms, and enterprise environments. ISO 27001 & ISO 9001 Lead Auditor certified (IBC/ACCREDIA accredited). I don't hand you a report and disappear. I implement the fix. 🔧 LINUX INFRASTRUCTURE & DEVOPS Server Administration & Performance - Linux (Debian, Ubuntu, CentOS/Rocky, AlmaLinux) — tuning, troubleshooting, production hardening - Apache/Nginx optimization, Varnish, database performance (MySQL/MariaDB replication) - Virtualization: Proxmox clusters, KVM, LXC containers DevOps & Automation - CI/CD pipelines, infrastructure automation, Ansible playbooks - Custom monitoring and alerting systems (Zabbix, Prometheus, Grafana) - Backup architecture with integrity verification and disaster recovery testing Web Hosting Platforms - cPanel/WHM expert, Plesk, DirectAdmin, ISPConfig - Mail systems: Postfix/Dovecot, spam filtering, deliverability and reputation repair - High-availability and load-balanced web environments (HAProxy, Nginx upstream) Cloud & Migrations - AWS, Google Cloud, DigitalOcean, bare-metal datacenter - Zero-downtime migrations — including 50GB+ mail servers with zero data loss - BGP routing, datacenter networking (Huawei VRP, GRE tunnels, failover) 🔐 SECURITY & COMPLIANCE Infrastructure Security - Firewall design and deployment: OPNsense, pfSense, iptables/nftables - Server hardening, intrusion detection, DDoS mitigation - Incident response, forensic analysis, post-breach recovery Compliance & Auditing - ISO 27001 Lead Auditor — IBC/ACCREDIA accredited certification - ISO 9001 Lead Auditor - NIS2 / D.Lgs. 138/2024 compliance assessment and implementation roadmap - GDPR technical measures — real infrastructure changes, not just documentation - ISMS implementation for SMBs (practical, scalable, without enterprise overhead) Why this matters: most compliance consultants understand the framework, not the stack. I run the gap analysis and implement the remediation. One engagement, not two. 🎯 WHAT MAKES ME DIFFERENT No fluff communication — I tell you exactly what is broken, why, and what it costs to fix. Production-safe approach — changes tested and staged before touching live systems. Full documentation — every engagement ends with clear, human-readable documentation your team can use without me. Long-term architecture thinking — I build systems to last, not patches to close tickets. 🏆 RECENT WINS E-commerce platform: page load 8 seconds to 800ms (10x improvement) Stopped a 500K+ req/s DDoS without service interruption Automated backup testing pipeline — caught 6 silent backup corruptions before disaster NIS2 compliance roadmap for Italian SMB: full implementation in 4 weeks ISO 27001 gap analysis: 87 findings, fully remediated and compliant in 3 months BGP migration from legacy ISP to dual-transit with zero downtime 📋 WHEN TO HIRE ME Emergency situations: - Server down or severely degraded - Active breach, hacked server, malware containment - Failed deployment with business impact Planned projects: - Infrastructure audit and security hardening - ISO 27001 / NIS2 compliance implementation - DevOps pipeline setup or optimization - Cloud or bare-metal migration - Ongoing managed infrastructure with real SLAs NOT a good fit if you need someone who rubber-stamps a checklist and moves on. I dig into root causes and fix them properly. This takes slightly longer and costs more. It is worth it. 📬 AVAILABILITY Taking new projects — limited capacity for ongoing engagements. Emergency response: typically within 4-6 hours on business days. Message me with your specific problem, timeline, and budget. I respond with clear next steps, no vague proposals.
