From CNC Control Systems to Custom Business Apps

Specialized support for SINUMERIK commissioning as well as tailored Java and Kotlin solutions for manufacturing, commercial, and digital processes.

35+ years of SINUMERIK experience
15+ years of Java software development
Robust solutions for 24/7 operation

“True solutions arise
when you listen to the user.”

There are many software packages on the market, but do they always fit 100%?
Software is only effective when everything fits together.


In industry and software development, results count. With over 35 years of hands-on experience with SINUMERIK, I know the exact requirements directly at the machine. At the same time, I leverage my 15 years of Java programming and Android development with Kotlin not only for manufacturing, but for building robust software and app solutions of all kinds – pragmatic, efficient, and smooth.

Real-World Projects

Migration SINUMERIK 840D sl → SINUMERIK One

An existing machine needed to be modernized. This required migrating the control system from SINUMERIK 840D sl to SINUMERIK One while complying with the Machinery Regulation (EU) 2023/1230.

Automated Maintenance Ticketing System

Maintenance operated primarily on ad-hoc requests; work orders (such as machine downtime and maintenance) were hard to track. Actual efficiency remained unclear while operational costs rose uncontrolled.

Fully Automated Production Workflow

Orders from an online shop had to be manually translated into production jobs. There was no feedback loop from machines to the sales system regarding production status.
