Why Vendor-Independent
Vendor independence keeps you flexible: no lock-in, transparent operations, and the ability to audit every layer. Open-source software is the foundation, but the goal is business outcomes—predictable costs, security you can verify, and systems you can extend or migrate at any time.

Reference Architecture
A representative stack: hardened OPNsense perimeter feeding platform services (Caddy, Zabbix, GLPI, Grafana, VoIP) with Proxmox compute, PBS backups, and managed Linux workloads.
How Engagements Work
We map your current infrastructure, objectives, and constraints, and agree on priorities.
Create a detailed plan with architecture diagrams, risk register, and automation scope.
Implement using Git-backed playbooks, with peer-review and change tracking.
Roll out observability and documentation, transition operations, and offer ongoing support.
FAQ
What infrastructure sizes do you support?
From single-site deployments to multi-region environments spanning tens of nodes. The guiding principle is reproducibility and strong storytelling through documentation.
How are engagements scoped?
Most projects begin with a short paid assessment that leads into either a fixed-scope delivery or a retainer for ongoing support. All automation artefacts stay in your repository.
Do you provide training?
Yes. I deliver handover workshops, write runbooks, and mentor teams so they are comfortable maintaining the platform after go-live.
