Linux servers
debian · ubuntu · rhel
Installation, performance tuning, maintenance. Auditing third-party configs without unnecessary rewrites. If it runs, don't touch it.
- migration from shared hosting to own VPS
- SSH hardening, fail2ban, unattended-upgrades
- tuning postgres / nginx / apache
- second opinion on third-party config
Virtualisation
proxmox ve · zfs · pbs · xen
Hardware consolidation, snapshots, HCI with ZFS. VMware migration without panic — we know what 2024 licensing looks like.
- 3+ node cluster design with HA
- VMware → Proxmox migration
- Proxmox Backup Server + offsite
- ZFS replication between sites
Firewall & VPN
opnsense · wireguard · openvpn
Network segmentation, multi-WAN, IDS/IPS, remote access via WireGuard. Done with OpenVPN agony and IPsec escapades.
- VLAN topology design for SMB
- WireGuard for 5–80 people
- multi-WAN failover
- Suricata IDS with low-noise alerts
Nextcloud & groupware
nextcloud · onlyoffice · talk
Your own cloud instead of Microsoft 365. File sharing, calendars, contacts, OnlyOffice, video calls. No per-seat licences.
- migration from M365 / Google Workspace
- SSO via Keycloak / LDAP
- OnlyOffice for co-editing
- S3 backend for large datasets
Monitoring
zabbix · nagios
See problems before the client calls. Alerts without noise, meaningful dashboards. One view, not ten.
- Zabbix self-hosted
- SMTP / Signal / SMS gw integration
- SLA reports for management
- night escalation via oncall
3-2-1 Backups
proxmox backup · restic · rdiff-backup
Regular. Off-site. And most importantly tested restores — we know they work. A backup we haven't tested restoring isn't a backup.
- PBS + offsite over WireGuard
- quarterly restore drill
- immutable snapshots (zfs / ransomware-proof)
- retention by data type

kickoff
Contract, access, first commit to git.
I don't do
-
01
Microsoft 365 as a strategic platform
A trap, not a strategy. Your own mail server pays for itself within a year.
-
02
SharePoint, Teams governance, "digital transformation"
Renaming a folder to "workspace" doesn't fix the process underneath.
-
03
Windows Server domain services as primary
AD in 2026 = debt, not investment.
-
04
Web design, SEO, copywriting, "branding"
Can't. I'll recommend three people who can.
-
05
SaaS reselling ("we'll give you a license at 30% off")
Nobody belongs between you and your data.
-
06
24/7 hotline without a specific agreement
At night I sleep. You should too.
-
07
Weekly status call with PowerPoint
When something burns, you call. When nothing burns, a slide won't help.
This isn't a list of what I can't do. It's a list of what I won't sell you.
Not in the list? Ask.
Sometimes I do things that haven't made it here yet. Send a few lines.
