20+ years building predictable, secure and fast platforms. Linux operations, automation (n8n), databases (MariaDB/MySQL & PostgreSQL), web hosting at scale, and real-time monitoring with Grafana.
Typical engagement outcomes; exact results depend on scope and baseline.
Hands-on operations with clear ownership, measurable KPIs and zero-surprises communication.
Debian, Ubuntu, Alma/Rocky, RHEL. SSH/SFTP chroot, systemd, users/quotas, EFI/RAID, XFS/EXT4, encryption, resource limits.
Bash workflows, rotational backups, rsync incremental with retries, integrity checks, n8n webhooks, Telegram alerts, PostgreSQL logs.
Tuning (mysqltuner/perf_schema), replication (Master-Slave), binlogs & sync, slow query analysis, per-DB dumps & offsite retention.
CSF/IPTables, Fail2ban, CrowdSec scenarios, VPNs & port-forwarding, round-robin LB, GeoIP policies, abuse handling & reputation.
Proxmox, Virtualizor, SolusVM, cPanel/Plesk/Hestia/CyberPanel. Apache/Nginx, PHP-FPM pools, SSL (Let’s Encrypt), HTTP/2/3 QUIC.
Grafana dashboards (CPU/RAM/disk/services/security), alert routing, GitLab + Jenkins (Docker), controlled deploys & hooks.
Environment audit, KPIs, risks & priorities. Clear scope and owners.
Architecture, runbook, rollback and timeline. Communication cadence.
Hardening, automation, tuning & tests. Documentation as we go.
Observability, alerts, incident response, continuous improvement.
