Reliable IT infrastructure — from servers and networks to the cloud
I'm Jacek Rokicki. I design, deploy and maintain Linux and BSD systems, Proxmox VE virtualisation environments, MikroTik-based networks and infrastructure on AWS, Azure and Google Cloud.
Services
From a single server and an office network to distributed cloud environments.
Linux and BSD administration
Configuring, securing and maintaining Linux and BSD servers.
Proxmox VE virtualisation
Installing, configuring and maintaining Proxmox VE environments — from single servers to clusters.
Network design and maintenance
Wired and Wi-Fi networks — from design and deployment to ongoing maintenance.
MikroTik deployments
Support with deploying and configuring MikroTik devices running RouterOS.
Cloud: AWS, Azure and Google Cloud
Designing, deploying and maintaining public cloud environments with a focus on security.
Migrations: on-premises ↔ cloud
Moving services from your own server room to the cloud — and back again when that makes more sense.
DevOps: Kubernetes, IaC and CI/CD
Automation, containerisation and delivery pipelines.
PostgreSQL administration
Installing, configuring, replicating and maintaining PostgreSQL databases.
Audits and security
Reviewing infrastructure for security, reliability and good practice.

How I work
The principles behind every project.
Direct contact
You work with me directly — no account managers, no hand-offs between departments.
Everything as code
Server, network and cloud configuration lives in code, so every change is repeatable and has a full history.
Secure by design
Least privilege, hardening and access control are part of the design, not an afterthought.
Documentation and knowledge transfer
I document what I build so your team can understand it and evolve it on its own.
