About

I am an independent engineer registered as a sole trader (OSVČ) in the Czech Republic. I design, build and operate server infrastructure — and write the software that runs on it.

I work with companies across the EU: from small offices that need a reliable network to product teams that need CI/CD, monitoring and on-call support. One contact, full responsibility, clear documentation.

How I work

  1. 01

    Audit

    I review the current state: servers, network, code, risks. You get a short written report.

  2. 02

    Plan

    Clear scope, milestones and a transparent estimate — before any work starts.

  3. 03

    Build

    Implementation, automation and documentation. Every change is versioned and reproducible.

  4. 04

    Support

    Monitoring, updates and maintenance with an agreed response time.
