About

I build computational design tools for architects and designers. My central interest is constraint-based design — systems where the creative act is formulating rules and relationships rather than producing form directly. I co-created Monoceros, the only Wave Function Collapse solver built for architecture (Grasshopper, 22,000+ downloads), and have spent 6 years developing theory and practice around discrete spatial assembly. I also spent 3 years as CTO of a deep-tech startup, building automated spatial layout systems using constraint satisfaction, evolutionary algorithms, and multi-objective optimization. I've taught computational design at UCL Bartlett, University of Toronto, and Academy of Architecture Amsterdam, led 50+ international workshops, and in 2012 curated the Slovak and Czech pavilion at La Biennale di Venezia. Currently developing the next generation of constraint-based design tools. Open to consulting engagements, teaching collaborations, and the right technical leadership role in computational design, design technology, or applied research.

Experience

  • Founder at Monoceros Tools
    Apr 2026 - Present · 3 mos

    Monoceros is the only Wave Function Collapse solver built for architecture - a Grasshopper plug-in for discrete spatial assembly where designers define parts and connection rules and the solver fills any envelope with valid, gap-free arrangements. Originally co-created with Ján Tóth at Subdigital in 2020, now developed independently as a commercial product with free and paid tiers. 22,000+ downloads.
