About me
My name is David and I have been a freelance IT consultant since 2023. What started as a side job while I was studying IT has now been my main job for quite some time. I help companies to set up and secure their IT infrastructure, from requirements analysis and concept development to implementation and monitoring. It doesn't matter whether it's on-premise or in the cloud! Feel free to contact me for an initial consultation.

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.
