Future-proof your
Digital Systems for the Built Environment. Empower your design practice with computational design, AI, and data-integration solutions.
Parametric Systems
Turn Grasshopper logic into robust systems that drive design decisions, not just geometry.
BIM & Data Platforms
Unify models, metrics, and project data into structured, reusable digital foundations.
Web Tools for AEC
Custom web applications that make complex design workflows accessible across teams.
Automation & AI
Targeted automation and AI where it actually reduces manual work and operational risk.
Marijn Luijmes
AEC Application Developer
I work at the intersection of architecture, parametric design, and full-stack development. My focus is on building reusable systems that help AEC teams explore scenarios, understand trade-offs, and make better decisions early in the design and development process.
