I initially started working as a freelance IT consultant and service provider alongside my studies in electrical engineering and information technology, specializing in data technology. Demand quickly exploded, which is why I have been doing this job full-time for quite some time now. Since 2023, I have helped countless customers (mainly SMEs) in Germany and internationally to modernize their IT and create new infrastructures.

I needed an urgent website backup and he delivered fast and professionally. Communication was clear, everything was done exactly as promised, and he even double-checked that the backup was working properly. Reliable, efficient, and stress-free service.

David did an excellent job helping me ensure Proxmox and pfSense were working properly with the vLAN and VPN configuration I needed. He's very well versed in these technologies, how they work together and the best practices needed to avoid issues in the future.

David hat unser Synology NAS perfekt eingerichtet sodass wir von unreal problemlos und schnell Zugriff haben. Zudem hat er unser Backup System aktualisiert und Verbesserungsvorschläge gegeben. Jederzeit wieder. Sehr zu empfehlen.

David is very knowledgeable and was able to immediately address the issues I was facing in pfSense. He not only resolved everything, but explained it along the way so I could better understand what's needed in the future. I will definitely hire him again.
