Backend intelligence meets immersive magic.
As an XR and AI Systems Engineer, I build intelligent backends and
develop immersive VR/AR experiences.
I connect both into applications that engage your users and bring your vision to life.
What I deliver: from AI pipelines to immersive experiences
Immersive User Experiences
VR/AR/XR development
Design and development of immersive apps with Unity that captivate. Expertise in Unity Engine for VR/AR/XR development, 3D rendering, and performance optimisation.
Mobile & cross‑platform apps
High‑performance apps with frameworks like Flutter for a seamless user experience across platforms.
Spatial & voice UI/UX
Intuitive interaction models for the next generation of spatial and voice‑driven interfaces in immersive environments.
Self‑hosted backend intelligence
Architecture‑as‑a‑Service
Tailored, self‑hosted AI & backend solutions for creative studios, indie devs, and data‑sovereign organisations.
Self‑hosted AI backend systems
Design and implementation of intelligent AI systems — from LLM, RAG, and TTS/STT pipelines to automated agent workflows with token‑based access controls — fully local and data‑sovereign.
Scalable, self‑hosted infrastructure
Robust, secure, fully self‑hosted stacks for modern containerised applications with Kubernetes and Docker.
My tech stack & expertise
I specialise at the intersection of self‑hosted AI technologies and immersive experiences — from backend architecture to the final pixel. These core technologies power the services above and ensure modern, robust, and data‑sovereign solutions.
Immersive frontend development
Interactive VR/AR/XR apps with Unity and C#: high-fidelity graphics, performance tuning, and spatial UI for real-time 3D.
- Unity (C#), OpenXR & SDKs (Meta Quest, Pico)
- Real-time 3D rendering, shaders & VFX
- Cross-platform immersive app development
- Spatial UI/UX design & prototyping
Intelligent backend systems
Design and implementation of intelligent services that focus on AI-driven automation and agent workflows. Using no-code tooling or Python, these self-hosted systems enable data-sovereign LLM integrations, efficient vector databases, and webhook-driven processes.
- Vector databases (PostgreSQL, Qdrant)
- LLM & RAG pipelines for generative AI
- Agentic Workflows with LangChain & PydanticAI
- Process automation & tool integration (n8n)
- API design (REST) & microservices
Cloud-native architecture & DevOps
Robust, scalable infrastructures with Kubernetes and Docker. Open-source first for data sovereignty and self-hosting.
- Kubernetes (K8s) & Docker containerisation
- Infrastructure as Code (Terraform)
- Cloud-native & self-hosting strategies
- Linux system administration & shell scripting
How we work — clear, focused, outcome‑driven
The process explains the how — only after the what is clear. Each phase delivers a tangible, usable outcome.
Understand & plan
We align on goal, audience, and expectations and create a clear plan.
Outcome: Simple project outline with time and effort.
Build the core
We create the key function that makes the experience work.
Outcome: Usable, tested building block.
Make it tangible
The interface brings everything together into a coherent experience.
Outcome: Clickable prototype you can try.
Refine together
We test with real users and polish it for everyday use.
Outcome: Ready for launch.
My pipeline implementations as products
AI Builder Stack
A fully self‑hosted app stack for AI automation and agent-based workflows, developed and tested in my own homelab. Built for data‑sovereign developers, activists, and small organisations needing an alternative to cloud AI tools. 100% open‑source. No subscriptions.
The Hubs Stack: Your Metaverse
A fully self‑hostable infrastructure for immersive 3D worlds, based on the Hubs Foundation open‑source project. As a “Blender‑native” platform, creators can build and manage virtual rooms directly from Blender. Full control of your data on your own Hetzner instance — developed and tested in my own setup.
About me: a Creative Systems Architect’s path
My journey didn’t start with code but with images. As a 3D artist—and later as a founder building XR history experiences—I learned how to create worlds that captivate. I love building with Unity, experimenting with Flutter, and crafting the right user interface. My Unity expertise spans the full pipeline from concept to performance optimisation for immersive apps.
Over time, it became clear: the frontier of innovation isn’t just visual—it’s the intelligence of the system. I kept hitting walls with monolithic cloud services and realised the future is sovereign, flexible, AI-driven architectures.
My work is the synthesis of that journey—from Kubernetes-based system architecture to the final pixel in a VR headset. I build the invisible machines that make the visible magic possible.
