## Focus areas

Daniel Plominski works on IT infrastructure, IT security and applied AI:
virtualisation and storage platforms, network and firewall architecture, and
language models running on owned hardware rather than rented from a hyperscaler.
Digital sovereignty is the common thread. He was head of IT at a medium-sized
company from 2017 to July 2026, responsible for the IT team and for the systems
behind 440 employee workstations. The building blocks of his work are Proxmox VE,
Ceph, Palo Alto firewalls and open-weights language models.

- Virtualisation and storage: Proxmox VE clusters with Ceph block storage,
  designed for live migration and planned maintenance windows.
- Network and firewall architecture: Palo Alto firewalls, network segmentation,
  tiered Active Directory and an internal PKI.
- Security operations: SIEM and XDR, ISO 27001 and NIS2 readiness, business
  continuity management based on BSI 200-4.
- On-premise AI: open-weights language models on dedicated GPU hardware,
  retrieval-augmented search across internal documents, speech recognition and
  synthesis.
