About Martin

Do you want to integrate AI meaningfully into your product or media processes – but don't know where to start or how to manage costs, architecture, and quality?

I support companies in building AI-powered video, media, and XR systems from idea to productive implementation.

With over 20 years of experience in 3D, XR, and media development, as well as in-depth practice in Generative AI, Python, AWS, and Google Cloud, I develop scalable solutions that not only work technically but are also economically sensible.

My focus areas:

• Conception and development of AI video and content pipelines
• Integration of OpenAI, Gemini, image, and video models
• Architecture of cloud-based AI systems (AWS / GCP)
• Cost optimization of AI workflows
• WebXR and 3D web applications
• Prototyping new AI features for SaaS products
• Technical consulting for startups and agencies

I work in a structured, pragmatic, and product-oriented manner. Instead of isolated features, I develop well-thought-out systems with a clear roadmap, clean architecture, and a realistic scaling plan.

Typical projects:

– Development of an AI video generation platform
– Integration of generative AI into existing web products
– Development of prototypes for investors or internal validation
– Optimization of existing AI pipelines in terms of performance and costs

As a founder, I understand not only the technology but also business realities, budget pressures, and time-to-market. My goal is not code for code's sake, but measurable progress for your product.

If you want to use AI strategically and sustainably, I am happy to support you.
