Technical execution, not just consulting
I don't only design solutions — I implement them and, on request, run them.

About Cebesco
Technically grounded, pragmatic in approach
Behind Cebesco stands Christian Berggrün — mechatronics engineer, software and web developer from Braunschweig, Germany.
My background is automation technology: understanding complex systems, analysing problems precisely, building robust solutions. I now use that mindset to help SMBs build sovereign open-source cloud environments.
Cebesco doesn't stand for “open source good, Microsoft bad”. I take a sober look at what makes sense for your specific case. Sometimes that's a full migration to Nextcloud. Sometimes it's a partial move. And sometimes it's the recommendation to leave things as they are.
What matters to me is that solutions are understandable, maintainable, and documented — even when someone else takes over later.

How I work
Honest assessment
If a migration doesn't make sense, I say so. Even when it goes against my own engagement.
Maintainability over cleverness
A plain, robust solution beats an elegant construct only I understand almost every time.
Direct contact
No agency loops, no rotating contacts. You talk to the person who knows your environment.
Own products and developments
Alongside the services for clients, Cebesco develops its own software projects. They serve to practically test reusable components, integration patterns, and operational processes — which in turn benefits the quality of client work.
Salonero — Salonero is a Cebesco SaaS product, a scheduler for hair and beauty salons, built entirely in Rust and in productive use for some time. More at salonero.de.
Further in-house software projects are in development or planning. They are not a separate business area but a technical foundation for client work.
