Back to original languageAbout Marvin
I design and develop custom interactive experiences: games, playable prototypes, immersive experiences, and real-time applications augmented by artificial intelligence.
My playground: Unity (my preferred engine), WebGL, Three.js, virtual and augmented reality, and the integration of agentic AI into interactive environments. I don't just code: I think about game design, technical architecture, and creative direction to deliver products that work and make an impact.
What I bring to your projects:
On the corporate side, I assist large groups in creating interactive prototypes, gamified experiences, and branded platforms. I deliver turnkey solutions: from design to deployment, with solid technical documentation and an architecture built to last.
On the video game side, I am developing my own PC title (Survival God Game in Unity, Steam page live) through my studio Oneiric Tales. This dual role allows me to bring the rigor of a product developer and the creativity of a game designer to each client project.
My areas of intervention:
- Rapid prototyping of games and interactive experiences (WebGL, Unity, mobile)
- Gamification and branded experiences for events, marketing, or training
- Real-time 3D applications for the web (Three.js, WebGL, React Three Fiber)
- VR/AR experiences for visualization, training, or entertainment
- Integration of generative and agentic AI in interactive environments (intelligent NPCs, adaptive narration, procedural systems)
- Technical direction and architecture of interactive projects
Tech stack:
Unity (C#) · Unreal Engine · Three.js · WebGL · React / Next.js · TypeScript · Node.js · Express · PostgreSQL · Prisma · Docker · FMOD Studio · VR/AR (Meta Quest, ARKit, ARCore)
AI Tools:
Claude Code · Windsurf · LLM API Integration · Agentic Workflow
