Expertise · DevOps and infrastructure

I make software observable and recoverable in its target environment, not merely buildable.

I build verifiable release and handover workflows by bringing service configuration, health checks, logging, virtualisation, backups and rollback steps into the project’s technical scope.

What I do

DevOps and infrastructure

Release reliability

CI checks, services managed with Nginx and systemd, health checks and logging; controlled releases with a rollback plan.

Servers and virtualisation

Linux and Windows Server; virtual servers on Microsoft Hyper-V and Proxmox VE planned around service dependencies.

Backup and recovery

Backup targets with Veeam Backup & Replication, automated backups and rollback steps designed for operational continuity.

Mail and web servers

Domains, DNS, SSL, web publishing and enterprise email; Hestia, Exim, Mailcow and SPF, DKIM and DMARC configuration.

Which infrastructure technologies do you use?

Linux, Windows Server, Microsoft Hyper-V, Proxmox VE, Veeam Backup & Replication, Nginx, Apache and Hestia.

Can you set up enterprise email?

Yes. Mail servers with Exim, Mailcow and Roundcube, set up together with DNS, SPF, DKIM, DMARC and TLS configuration.
