Three areas where I can help

From designing the infrastructure, through securing it, to running it day to day with an agreed response time.

  • Infrastructure & DevOps

    Private cloud, containers, infrastructure as code, CI/CD, backup and DR.

    See the details

    What you get

    • Design and rollout of a private cloud on Proxmox VE with a Ceph cluster and high availability.
    • Application or Docker clusters, including an image registry.
    • Infrastructure as code: Ansible and AWX for configuration, Terraform for cloud resources.
    • CI/CD pipelines in GitLab CI: build, test, deploy and roll back.

  • Networking & security

    Segmentation, routing, firewalls, VPN, WAF, vulnerability management, ISO 27001.

    See the details

    What you get

    • Addressing, segmentation and routing design, documented in NetBox.
    • Dynamic routing configuration, including BGP, and redundant links.
    • Fortigate or IPFire firewall deployment together with access policies.
    • Remote access: IPsec VPN and zero-trust networks on Tailscale.

  • Managed operations (SLA)

    Monitoring, high-availability clusters, incident response, performance tuning.

    See the details

    What you get

    • Monitoring in Zabbix with Grafana dashboards and thresholds tuned to real traffic.
    • Incident response within an agreed time, with communication while the incident is ongoing.
    • High-availability clusters: Percona XtraDB Cluster, HAProxy, replication and failover.
    • Performance tuning: SQL queries, caching and application server configuration.

How I work

Four steps, always in this order

No audit means no design, no design means no rollout. This order saves money by the third step.

  1. Step 01

    Audit and analysis

    An inventory of what is actually running and a risk list ordered by business impact. Without this step everything that follows is guesswork.

  2. Step 02

    Architecture design

    The target shape of the environment, with cost, schedule and a rollback plan. Decisions are made before the rollout, not during it.

  3. Step 03

    Implementation

    Staged delivery, with configuration described in Ansible and Terraform. Every step is repeatable and reversible.

  4. Step 04

    Operations and monitoring

    Monitoring with thresholds tuned to real traffic, updates, restore testing and a report on the state of the environment.

What I actually do day to day

The full technology matrix, project experience and certifications. No vague claims about “familiarity with operating systems”.
