Internal process solution
Recurring steps, data and roles are combined in one understandable tool.
Custom instead of cumbersome
I build applications, tools and interfaces for special requirements—from prototype to supported operation.

Custom instead of cumbersome
Software follows your real workflow instead of forcing the organisation into an unsuitable standard process.
Recurring steps, data and roles are combined in one understandable tool.
Software connects content, devices and operation into a reliable whole.
Interfaces reduce transfer work while preserving human approvals.
We clarify the goal, current situation, users and essential requirements.
You receive a rough framework for implementation, scope, timing and price.
The project is built transparently, with regular feedback whenever useful or requested.
The solution is delivered or installed, tested and explained clearly.
Support for agreed features and later extensions remain available.
Source code, usage rights, hosting, stores and operation are agreed in writing for each project.
IT-Service Castel
Primarily small and medium-sized businesses, facilities and teams. Ambitious personal passion projects are welcome too.
Yes. On-site work is available in Berlin and Brandenburg and, depending on the project, throughout Germany. Travel effort and cost are agreed in advance.
Billing depends on the task, scope, risk and required support. You receive a transparent framework before work starts; there are no blanket bargain promises.
You can enquire at any time. Guaranteed acceptance, response or restoration times apply only when explicitly agreed. Any surcharge is confirmed before paid out-of-hours work starts.
Directly by email, phone, WhatsApp or through the Castel community on Discord. The form only needs your name, email and message.
