Why Open Source
Open source gives you freedom: no vendor lock-in, full visibility into the stack, and a community that never stops improving the tools we rely on. My approach centres on that freedom—you keep control of your data, know exactly how your systems operate, and benefit from automation that can be audited line by line.
Service Pillars
Automation & Orchestration
Ansible-driven provisioning for servers, applications, and network services.
- GitOps-style workflows & CI pipelines
- Idempotent playbooks with change tracking
- Reusable roles for multi-site deployments
Full-stack Builds & Monitoring
Delivering production-ready stacks from bare metal to observability.
- Proxmox VE & Proxmox Backup Server rollout
- GLPI, Zabbix, Grafana, and Wazuh integration
- Lifecycle management & policy-as-code
Security & Resilience
Hardening and continuity planning that keeps you online and compliant.
- OPNsense firewalls, VPN, and IDS deployments
- Backup, restore, & site-to-site replication strategy
- Continuous patching pipelines & drift detection
Consulting, Audits & Support
From architecture reviews to ongoing maintenance retainer engagements.
- Infrastructure health checks & documentation
- Operations runbooks and mentoring for teams
- Incident response and escalation support
Technology Stack
Focused on battle-tested, community-driven platforms.
Recent Engagement Highlights
Self-hosted Service Hub
Built an end-to-end platform using Proxmox, GLPI, Zabbix, and Grafana for an MSP that needed full ownership of customer tooling.
- Infrastructure-as-code with Ansible and CI
- Automated onboarding for new tenants
- SLA visibility improved by 60%
Security Perimeter Refresh
Replaced legacy edge firewall with OPNsense, added Wazuh for security telemetry, and rolled out enforced credential hygiene.
- Zero-trust VPN with MFA
- Centralised alerting and threat feeds
- Documented disaster recovery playbooks
Backup & Continuity Modernisation
Introduced Proxmox Backup Server and immutable ZFS snapshots for a SaaS provider running Debian and Fedora clusters.
- Recovery objectives met in testing within minutes
- Automated verification jobs and reporting
- Stakeholder training for operational readiness
Reference Architecture
A representative stack: hardened OPNsense perimeter feeding platform services (Nginx, Zabbix, GLPI, MainWP, Grafana) 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.
