Hi. I am Markus —
(Berlin^DE ↔ Porto^PT) based
Senior Design Engineer & Full-Stack Developer.

In 2026 I began releasing a growing set of open source projects that reflect the way I like to work: close to products, systems, and real constraints. They include ai11y, a structured UI context layer for AI agents that makes existing interfaces understandable and actionable; market-ui, a design system for interfaces shaped by price, time, and competition, built for transactions, auctions, and dynamic marketplace logic; and hashed-gems, a React avatar component and hosted image API for generating deterministic gemstone avatars from any string seed; and JobNest, a privacy-first job application tracker that helps people stay on top of their application progress without compromising their data.

Built and scaled the largest open multi-chain generative art platform, used by 25k+ artists and collectors, enabling the creation of over 2M artworks and $100M+ in sales. The focus was on making complex on-chain interactions intuitive without hiding their underlying mechanics — developing performant interfaces, reusable UI systems, and evolving the architecture into a unified monorepo to improve scalability, maintainability, and developer experience.

Building at the intersection of design and engineering, delivered interactive systems for cultural and enterprise clients, translating complex UX and data-heavy interfaces into scalable, production-ready applications used in real-world decision-making. Shaped technical architecture, design systems, and developer workflows across projects, and progressed into a lead role, helping grow the team from 4 to 12.

Working across software, hardware, and spatial design, I designed and built interactive installations and kinetic sculptures for public exhibitions. The work was hands-on and experimental, turning conceptual ideas into technically viable systems. I developed real-time, performance-sensitive software driving physical installations, and built pipelines connecting sensors, kinetic modules, and rendering systems, in close collaboration with designers and engineers.

Graduating in 2015 in Interface + Interaction Design, I focused on how interfaces help people understand and navigate complex systems. My thesis (Sprache / Algorithmen) explored how algorithmic logic shapes natural language, a line of thinking that has since become central to modern AI systems.
