IT infrastructure & self-hosted business applications
Strategic technology consulting, thoughtful architecture and seamless integration.
I help businesses take control of their technology, built on open source and open standards for secure, flexible solutions that reduce costs and eliminate vendor lock-in.
Core Expertise
Real tools. Real implementations.
Infrastructure
Linux, Debian, Incus containers, ZFS/Btrfs storage. Hosted on European providers (Hetzner, Netcup, Scaleway, OVH). Built for isolation, snapshots, migration, and resilience.
Cybersecurity
CrowdSec, nftables, Fail2ban, Suricata, Wazuh. Layered security from network edge to application level. No single point of failure.
Backup & Disaster Recovery
Kopia, automated offsite backups to European storage, tested restores, documented recovery plans. Backups that aren’t tested aren’t backups.
Business Applications
Nextcloud, OpenCloud, SuiteCRM, Dolibarr, ERPNext, Collabora Online. Self-hosted alternatives that replace expensive SaaS subscriptions.
Communication
Mail servers (Postfix, Dovecot, Rspamd), VoIP (Asterisk), team chat and video (Element, OpenTalk). Self-hosted, private, fully under your control.
Web & Publishing
WordPress, WooCommerce, and Ghost. Design, performance optimization, security hardening, and hosting on properly configured Nginx/PHP-FPM stacks. Fast, secure, and built to handle real traffic.
How I work
From analysis to implementation.
A structured approach to technology that puts your business first.
Strategic Technology Consulting
Every engagement starts with understanding the business, not the servers. A thorough assessment of the current environment, the costs involved and the risks present. Vendor-neutral, objective and focused on what actually moves the business forward. Think of it as a second opinion on your IT.
Thoughtful Architecture
Once the direction is clear, solutions are designed around actual business needs. Open source, self-hosted where it makes sense, hosted in European data centers and composed of components the client owns and controls. No black boxes, no dependencies that can’t be walked away from.
Seamless Integration
This doesn’t stop at advice. Systems are built, migrated, secured and handed over. From deploying business applications to security hardening, backup strategy and disaster recovery. Every implementation is designed to run reliably and transition smoothly into daily operations.
