Services

I look after servers at every stage: installation and configuration, hardening, and day-to-day maintenance and updates.

• configuration and maintenance of Linux and BSD servers
• hardening and security updates
• automation of routine administration tasks
• troubleshooting performance and availability issues

I deploy and maintain environments built on Proxmox VE, from single servers to clusters. It is a stable, cost-effective platform for virtual machines and containers, without the licensing costs typical of commercial alternatives.

• Proxmox VE installation and configuration
• building and maintaining Proxmox VE clusters
• virtual machines and LXC containers
• backup and recovery with Proxmox Backup Server
• updates and ongoing maintenance

I design networks to be fast, secure and easy to extend, and then keep them running smoothly.

• network architecture and segmentation design
• routing and site-to-site connectivity
• Wi-Fi network design, deployment and maintenance
• IPv6 design and deployment
• topology documentation
• maintenance and troubleshooting

As an Official MikroTik Consultant, I help plan, deploy and evolve RouterOS-based networks.

• configuration of MikroTik routers, switches and wireless networks
• routing, firewalling and traffic management
• RouterOS upgrades and migrations
• review and optimisation of existing configurations

I have extensive experience designing and running AWS environments, backed by Professional- and Specialty-level certifications. I also work with Microsoft Azure and Google Cloud (GCP), so I can help you choose the right solution for your needs — whichever provider you use.

• cloud architecture design
• account security and access management
• cost and reliability optimisation

I help plan and carry out migrations from on-premises infrastructure to AWS, Azure or Google Cloud. I also help in the other direction: when cloud costs no longer add up, or when data needs to come back to your own servers. I prepare every migration so the cut-over happens with minimal downtime and with a rollback plan ready.

• environment assessment and migration plan
• choice of target architecture and cost estimate
• migration of servers, databases and applications
• moving services from the cloud to your own infrastructure, e.g. Proxmox VE
• testing, cut-over and rollback plan

For several years I worked as a DevOps engineer and co-designed the infrastructure architecture of services such as playnow.pl and player.pl. I apply that experience to automating infrastructure and deployments.

• Kubernetes clusters and application containerisation
• infrastructure as code (IaC)
• CI/CD pipelines
• configuration automation

I administer PostgreSQL databases so they stay fast, secure and resilient.

• installation and configuration
• replication and high availability
• backup and recovery
• performance analysis and tuning

I review servers, networks and cloud environments and turn the findings into concrete recommendations.

• audits of servers, networks and cloud environments
• security review of configurations
• report with prioritised recommendations
• support in implementing the recommendations

I set up monitoring that shows the state of your infrastructure and lets you act before users notice a problem.

• Zabbix and Prometheus deployments
• centralised logging (ELK)
• alerting tailored to your needs
• dashboards and reports
