Available to hire
I’m Thibault Montfray, a product designer and front-end engineer who loves building end-to-end experiences—from the moment a product idea becomes a working prototype to deployment and product life-cycle evolution. For years, I’ve focused on what makes interfaces feel right over time, blending strong design judgment with solid engineering so teams can ship high-quality products quickly.
In the AI era, I design directly into fast, AI-assisted iteration loops and also build my own tools and products to stay sharp on the technology I use for clients and collaborators. Whether I’m designing design systems at scale, modernizing complex interfaces, or orchestrating automation that removes repetitive work, I aim for fast delivery without sacrificing craft—so interactive value shows up within week one.

Work Experience
AI Product Design / Front-End Engineer - Expert IA Pilot at https://indiecrafts.dev
September 1, 2026 - Present• My studio, and the independent practice behind it since 2012. I take products from framing to deployment — architecture, interface design, front-end build — solo or embedded in client engineering teams.
• Design happens in code from day one — clients steer a working prototype, and structure is validated before a pixel is styled. It started as design thinking workshops and sprints translated straight into HTML/CSS prototypes: design as code, years before the term existed. Today it is AI-piloted, and far faster.
• End-to-end product development and deployment · websites, launch and event pages, light custom shops · dashboards and business application UIs · mobile and desktop apps in React Native and Electron · design systems documented and handed over in Figma and code · modernisation onto faster, more accessible technology · senior design-in-code reinforcement alongside your teams · automations for repetitive workflows.
• Clients include BNP Paribas Group, Vente Privée, SeLoger, L'Institut Français, Foroil and Aedle — companies, technical teams, independents and non-profits alike.
