In 2026 I started releasing a growing set of open source projects, including ai11y, a structured UI context layer for AI agents that makes existing user interfaces understandable and actionable; market-ui, design-system with declarative components 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.

Cześć. I am Markus —
a Berlin Porto-based Senior Design Engineer & Full-Stack Developer.
Since 2011 I've been working with data and information technology—both inside and outside the web. I thrive in modern design and coding environments, and when existing tools don't quite fit, I build my own.
Building the largest open cross-chain generative art platform, I focused on UI and UX for complex onchain flows. The goal was to make these interactions clear and intuitive without hiding their mechanics. With a strong focus on performance and consistency, I shaped reusable UI patterns that scaled with the product, and migrated the codebase from a distributed microservice architecture to a unified monorepo to improve developer experience, shared code, and maintainability.
Building at the intersection of design and engineering, I developed interactive web applications, tools, and real-time systems for cultural and enterprise clients. The work focused on translating complex UX concepts and data-heavy interfaces into scalable, production-ready systems. I shaped technical architecture and implementation together with designers and engineers, and built custom tools, data pipelines, and design systems used in both installations and criticial decision-making software.
Working across software, hardware, and spatial design, I designed and build 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 designing interfaces and user experiences for complex systems, creating interfaces for solving complex problems and shaping how people understand and navigate technical environments. My thesis (Sprache / Algorithmen) explored how algorithmic logic shapes natural language — a line of thinking that has since become central to modern AI systems.
