What My Clients Say
"The VR training measurably reduced our accident rate. We were particularly impressed by the close coordination during development — a working build every two weeks that we could test right away."
"The 3D configurator significantly increased our online conversion. Customers can now experience our products before they buy. The WebGL solution also runs on smartphones — that was important to us."
"Finally a freelancer who doesn't just code, but thinks along with us. Nicolai turned our vague brief into a well-thought-out AR app that our service technicians actually enjoy using."
"Our booth was the crowd magnet of the entire trade show. The interactive 3D application didn't just attract visitors — it generated qualified conversations that led directly to orders."
"We previously had bad experiences with a large agency. With Nicolai, everything was different: direct communication, fast responses, transparent billing. The serious game was delivered on time and on budget."
Why Work with Me?
You work directly with the developer who builds your project. No account manager, no agency overhead.
12+ Years of Unity Expertise
Not a generalist who "also does Unity sometimes." Unity is all I have been doing for over a decade. That means: less risk, better architecture, faster results.
Direct Communication
No project manager in between, no game of telephone. You speak directly with the person writing your code. Fast decisions, short paths, clear communication.
Flexible Collaboration
Fixed price or time & material. Full-time or part-time. Solo or as reinforcement for your team. I adapt to your project — not the other way around.

Frequently Asked Questions
My hourly rate ranges between 95 and 120 EUR depending on project scope. A small project or prototype starts at 8,000 EUR. Mid-size projects range from 20,000 to 60,000 EUR. Fixed pricing is possible with a clear scope. In the free initial consultation, I will give you a realistic figure — no guesswork.
You will have a prototype in 3 to 4 weeks. A mid-size project takes 2 to 4 months. Every 14 days you receive a working build to test — so you can see progress and adjust direction at any time.
No, not at all. Most of my clients are project managers, managing directors, or marketing leads — not developers. I explain everything in plain language and handle all the technical details.
Unity is particularly well suited for VR/AR, mobile, WebGL, and cross-platform projects. It is more lightweight, faster to iterate with, and covers most business applications optimally. For photorealistic AAA graphics, Unreal would be better — I will tell you that honestly.
Yes, regularly. I integrate seamlessly into existing teams and workflows. Whether as the sole developer or as reinforcement for your team — both work. White-label and direct client communication on request.
iOS, Android, WebGL (browser), PC (Windows/Mac), VR headsets (Meta Quest, HTC Vive, Pico), and AR (ARKit, ARCore). Unity enables cross-platform development — one project, multiple platforms, lower costs.
Step 1: Free 30-minute call. Step 2: Proposal with clear pricing and timeline. Step 3: Working builds and feedback rounds every 2 weeks. You have full transparency and control at all times.
You do. Full IP transfer, clean source code, documentation. German contract, NDA as standard. You can have the project continued by another developer at any time.
Yes, optionally. Many clients use maintenance contracts for regular updates, bug fixes, and further development. But you are not locked in — I can also hand over the project completely if needed.
Absolutely — I actually recommend it. Start with a proof of concept. Test the feasibility. If it works, we scale together. No risk, no all-or-nothing.
