UNITY DEVELOPMENT FOR BUSINESSES & AGENCIES
Help customers explore your products, train your team, or get an existing Unity project across the finish line. One senior developer, from first prototype to launch.
A few lines are enough. No finished brief needed.

01 / PORTFOLIO
Every project here runs in real time, right in your browser. Open one, change what you like and see what your customers would experience.
Enter the wind tunnel
NEWSIMULATION · 2026
A real-time aerodynamics lab in the browser. Set the wind speed, angle of attack and height, and watch the smoke show where the air speeds up, slows down and separates. Push the wing too far and it stalls.
Start the engine
PRODUCT EXPERIENCE
A product that explains itself. Rotate the engine, start it and click through fan, compressor, turbine and drive shafts.
YOUR PROJECT
A product demo, a configurator, a digital twin or VR training. Tell me what people should understand, and I'll show you how it could work.
02 / WHAT I BRING TO YOUR TEAM
Start with the outcome you need. I can build a complete experience or take on a focused part of an existing project.
Help buyers understand what makes your product valuable. Interactive demos, configurators and showrooms let them explore the details at their own pace.
Give people a place to practise, explore and learn by doing. VR training and AR guidance, designed around your users and the devices they will actually use.
Get an idea into a working prototype, improve an existing build or bring it to launch. Focused Unity development, interaction design, shaders and performance work.
What should people experience? Where will it run? We get clear on the audience, the constraints and the part you need me to own.
Working builds, direct communication and early answers to the difficult questions. You can show progress, test ideas and make informed decisions.
A considered experience, the agreed source code and the documentation your team needs. Ready for the next person, next phase or next platform.
04 / YOUR POINT OF CONTACT
I'm an independent Unity developer based in Karlsruhe, Germany. For more than 12 years, my focus has been C#, real-time 3D and the small interactions that make an experience feel right.
You work with the person who builds it. I can help shape the technical direction, question an assumption and take responsibility for the implementation — with your project's goals in mind.
[email protected]A FEW THINGS YOU MIGHT ASK
Yes. I work directly with businesses on product visualization, training and interactive experiences. I can help define the scope, choose the target platform and take your project through development and delivery.
Yes. White-label collaboration and NDAs are welcome. We agree on communication and responsibilities up front, including whether you want me to work directly with your client.
Yes. I can review the current build, identify technical risks and take on a clearly defined part of the work — from interaction development to visuals, performance or delivery.
Yes. Tell me what people should be able to do, who the experience is for and any deadline you have. We can work through platforms, assets and technical requirements together.
That depends on the scope, the target platform and the assets or code you already have. After clarifying the requirements, I can prepare a proposal with defined deliverables and milestones. We agree on the work before development starts.
Yes. It's a live browser-based 3D showcase, built with Three.js. You can rotate the engine, start the simulation and inspect its components. It demonstrates my approach to real-time visuals and interaction; Unity projects are built for the platform your brief needs.
It runs a real-time flow model in your browser. The smoke follows a computed flow field around the model, and lift, drag and the stall respond to wind speed and angle of attack the way you would expect. It is built to explain and convince, not to replace an engineering CFD study. For your product, we decide together how much physical accuracy the story needs.
05 / THE NEXT GOOD IDEA STARTS HERE
A new product experience, a training application or a Unity project that needs support. A few lines about your idea are enough to start.
Share the goal and any timing you have in mind.
I'll confirm fit, ask the useful questions and discuss availability.
