Anonymized examples from real client work.
Not every business wants to be named publicly. Many examples here are therefore intentionally described by situation and business impact instead of client name.
Industrial distributor, Bavaria
Billing and supplier mail stopped after a registrar move wiped SPF, DKIM and MX records.
Invoices and supplier communication stopped landing, creating same-day operational risk.
Rebuilt the DNS zone from exports, restored SPF/DKIM/DMARC, verified MX routing with Microsoft 365 and monitored delivery for 48 hours.
Outgoing and incoming invoices landed again the same day and the accounting backlog was cleared overnight.
Cloudflare DNS, Microsoft 365, DMARC monitoring, manual log review.
Same-day fix
DNS records, mail-routing notes and a short recovery summary.
Boutique studio, Rhine-Main
Five production sites ran on an unmanaged Debian VPS with root-level scripts nobody trusted.
Deployments were risky, outages were hard to trace and nobody wanted to touch production.
Provisioned a fresh Debian 12 host, containerised each project, added automated backups, tightened SSH access and documented deploy/runbooks.
Deployments are predictable, SSL renewals automatic and the studio finally knows what runs where.
Debian 12, Docker, Nginx, UFW, Hetzner Cloud, GitHub Actions.
1.5 days including handover
Runbooks, access notes and documented deployment flow.
Consulting duo, Berlin
A dated template with broken forms made the firm look unreliable and lost mobile enquiries.
Prospects could not trust the site and mobile leads were being lost quietly.
Redesigned the offer, wrote focused service copy, rebuilt the site in Next.js with bilingual content and hardened hosting.
Qualified enquiries returned within 48 hours of launch and edits no longer break layouts.
Next.js, Tailwind CSS, Vercel, Cloudflare proxy, documented CMS handover.
3 weeks including approvals
Editable content structure, launch checklist and update notes.
Property manager, Hamburg
MX records still pointed to the old host after a rushed migration, so tenant notices vanished.
Important notices disappeared and normal communication with tenants became unreliable.
Audited registrar history, synchronised DNS TTLs, configured fallback routing, added SPF/DKIM with the new provider and set up catch-all monitoring.
Inbox loss stopped immediately and the manager now has a documented playbook for future moves.
Netcup DNS, Google Workspace, Mail-Tester, uptime and SMTP monitoring.
4-hour remote session
Migration playbook, verified DNS records and follow-up checks.
