SÉBASTIEN PERRAULT
Computational Designer, Engineer and AI/data product builder bridging 20 years of AEC domain expertise with modern technology — parametric design, knowledge engineering, AI-augmented workflows, and SaaS product development.
Fluent across the full stack — from Grasshopper definitions and FEA scripts to Python data pipelines, Three.js renderers, and OAuth/Stripe SaaS infrastructure.
Designs and industrializes creative workflows through scripts, web components, and multi-agent AI systems.
Hybrid thinker — engineer's rigor with a designer's eye. Understands design systems, user experience, and visual communication.
Builder mentality in ambiguous environments. Defines roadmaps, recruits teams, ships products.
