Software that works. And that you understand.

I build and operate open-source solutions on European servers – transparent, sovereign, no lock-in.

Problems I solve

Your system has grown and no one dares to touch it.

Important changes take weeks because everything is interconnected.

Operations feel like luck, not control.

You want to get out of AWS, Azure, or GCP, but without chaos.

You need a new product, but no team to implement it reliably.

My services

Interim CTO

Problem

Your CTO is gone or overwhelmed – and you need someone to take technical responsibility without you having to worry about the details.

Solution

I take over technical leadership for a defined period: clear decisions, transparent communication, and a roadmap that fits your business.

Outcome

Less friction, clear responsibility, and visible progress – without you having to deal with technology.

Migration and Hosting (EU, Open Source)

Problem

Your server is old, expensive, or opaque – and you want to get out of US cloud dependency without chaos or downtime.

Solution

I bring your applications to European servers with open-source alternatives: sovereign, cost-transparent, and without lock-in.

Outcome

Data in the EU, traceable operations, and calculable costs – with minimal downtime and clear documentation.

Examples

  • Nextcloud or OpenCloud for sovereign file storage
  • Single Sign-on with Keycloak for central authentication
  • Automation with Ansible for reproducible infrastructure

Product Development and Implementation

Problem

You have an idea or a specific goal – but no team to implement it reliably without you having to worry about every detail.

Solution

I implement the software you need: from planning to handover, with a clear focus on your requirements.

Outcome

A product that is usable, scalable, and without dependencies – with documentation that you understand.

How I work

I work transparently and without jargon. You get clear decisions, traceable steps, and documentation that you understand.

My focus is on open-source solutions and EU hosting to minimize dependencies and maximize sovereignty.

I take responsibility for the entire project – from planning to handover – so you can focus on your business.

If we are not a good fit, I will say so openly and recommend a sensible alternative.

Why you can trust me

EU Hosting Instead of US Cloud Lock-in

Open Source Instead of License Blackbox

Documentation you understand

Secure and reproducible deployments

Risk minimization through transparency
