Last position:
Architecture and Programming for Automotive Test Bench Platform at Automotive Supplier
In this project, I was responsible for the design and implementation of a new, modular, and highly scalable test bench platform for an automotive supplier. My focus was on developing a robust system architecture and programming the associated software, with consistent use of UML modeling throughout. This structured approach made it possible to greatly increase the reusability of individual LabVIEW test modules and to significantly reduce development time for follow-up projects. I also integrated modern automotive standards such as CAN FD, LIN, and safety requirements, which made the solution future-proof.

Team Lead; Software Developer at Provider of industrial control systems for manufacturing and digital transformation
Industrial Communication | Proof of Concept: Controller-to-Controller Communication with OPC UA FX
Proof of Concept for OPC UA FX-based controller-to-controller communication between virtual programmable logic controllers (vPLC) on an industrial edge platform. A virtual test environment was set up on Debian Linux in two phases (including VMs and vPLCs), shared-memory communication (real-time information bus) was activated, and the RIB solution was integrated into a customized product firmware (including shared memory and PROFINET support) and deployed in containerized environments (Docker). Additionally, a virtual Ethernet connection was developed to simulate the network topology. Finally, commissioning, functional tests, sample application creation, comprehensive documentation, and customer support were completed.

About the technology
What PROFINET is
PROFINET is an industrial Ethernet standard used to connect controllers, field devices, drives, I/O, and sensors in automation systems. It is common in factories that need reliable data exchange, tight cycle times, and clear diagnostics. Many teams still refer to PROFINET IO when they mean the device communication layer.
Where it fits
- Machine and line automation
- PLC to remote I/O communication
- Drives, motion, and safety links
- Brownfield upgrades from PROFIBUS
- Industrial diagnostics and device replacement
It is often chosen when deterministic behavior and simple plant integration matter more than general-purpose IT networking.
Tooling and ecosystem
Strong professionals know the controller environment, device description files, network planning tools, and the diagnostic functions used during commissioning. They also understand how PROFINET relates to Ethernet switches, VLANs, managed network design, and time-sensitive traffic. In Germany, this often means working with mixed-vendor plants and clear documentation in English or German.
When freelancers help
Companies bring in freelance expertise when a new line is being commissioned, a plant is being expanded, or a network is failing in production. They also help with device integration, troubleshooting name resolution or topology issues, and converting older PROFIBUS setups to PROFINET. Short engagements are common when internal specialists are tied up with operations.
What strong experts deliver
Good specialists do more than make devices appear online. They verify naming, address assignment, device profiles, diagnostics, and network behavior under load. They can read error patterns, coordinate with electrical and automation teams, and leave behind a setup that is documented and supportable.
Signs you need PROFINET help
- Devices drop out or show intermittent faults
- New hardware must join an existing plant network
- A line needs faster commissioning
- Legacy fieldbus equipment must be migrated
- Diagnostics are too weak for maintenance to act on
For companies in Germany, on-site time is often useful during commissioning and fault finding, while remote support works well for review, design, and documentation.
Frequently asked questions
Everything clients usually want to know about PROFINET, in one place.
PROFINET is used to connect controllers, I/O, drives, sensors, and other plant devices over industrial Ethernet. It is a common choice for machine control, line automation, diagnostics, and coordinated motion. Many projects also use PROFINET IO to describe the device side of that setup.
PROFINET is the Ethernet-based successor most teams choose when they want more flexible networking, easier diagnostics, and better integration with modern plant infrastructure. PROFIBUS is still present in many plants, especially older ones, but PROFINET is usually preferred for new installations and many upgrade projects. A strong freelancer should understand both during migration work.
A strong PROFINET specialist usually knows PLC environments, industrial switching, device configuration, and network diagnostics. Experience with safety communication, drives, HMI integration, and brownfield migration is also valuable. In many plants, good documentation matters as much as technical setup.
PROFINET help is useful during commissioning, plant expansion, network faults, and migration from older fieldbus systems. Freelancers are also brought in when internal experts are busy with operations or when a short, focused diagnostic task needs fresh eyes. The best fit is often someone who can work with both automation and maintenance teams.
PROFINET work often benefits from on-site access during commissioning and fault finding because wiring, switches, and device behavior need to be checked in the plant. Remote collaboration still works well for network review, document checks, device list validation, and preparation before a site visit. In Germany, many projects use a mix of both.
PROFINET is the overall industrial Ethernet standard, while PROFINET IO usually refers to the cyclic controller-to-device communication used in automation. People often use the terms loosely, which is why both appear in project briefs and searches. A good specialist should be comfortable with the full stack, not only the device layer.
A strong PROFINET freelancer explains the network clearly, finds root causes instead of masking symptoms, and leaves clean documentation behind. Look for practical experience with commissioning, diagnostics, topology checks, and vendor-neutral troubleshooting. Good experts also ask about the plant layout, device types, and shutdown windows before they start.
PROFINET projects in Germany often involve industrial plants, mixed vendor environments, and tight coordination with maintenance or production teams. Some work is remote, but site presence is common during start-up and fault resolution. Clear communication in English is often enough, while German can help when the project involves local plant staff and documentation.
The average hourly rate of freelancers in Germany who have used PROFINET in their recent projects is 89 €, which corresponds to a daily rate of about 712 € based on an 8-hour working day.
Of the freelancers in Germany who have used PROFINET in their recent projects, 77% hold at least a Bachelor's degree, 45% hold at least a Master's degree, and 5% hold a doctorate.
On average, freelancers in Germany who have used PROFINET in their recent projects have 25 years of professional experience, with a single engagement typically lasting around 5.3 years.
The most common languages among freelancers in Germany who have used PROFINET in their recent projects are German (100%), English (96%), and French (19%).
The most common industries among freelancers in Germany who have used PROFINET in their recent projects are Manufacturing (100%), Automotive (50%), and Information Technology (50%).
The most common business areas among freelancers in Germany who have used PROFINET in their recent projects are Product Development (100%), Information Technology (77%), and Operations (65%).
