Objective
Create a robust, scalable product that could serve both small contractors and enterprise clients, without sacrificing simplicity.
The goals were clear:
Build a complete design foundation from zero.
Turn complex regulatory workflows into intuitive, human interfaces.
Establish a product vision strong enough to scale, and be recognized as a differentiator in the market.
Process
1. Product architecture
I collaborated directly with the CEO and CTO to map user journeys and define the product’s structure.
The goal was to streamline fragmented workflows, onboarding, document verification, project tracking, into a single, logical flow.
2. Design system & UI foundations
I established the entire design system in Figma, color tokens, components, typographic rhythm, interaction principles — and worked closely with the dev team to ensure pixel-perfect implementation and tokenized delivery.
3. Visual identity & product cohesion
Beyond UX, I designed the overall brand direction of Batis: minimal, structured, and focused on readability.
The visual identity became part of the company’s differentiation and was later reused as a foundation by Once For All’s design teams post-acquisition.
4. Team enablement
As the product scaled, I documented design patterns and contributed to onboarding future designers to maintain design quality and consistency across features.
Outcome
Batis became one of the most respected compliance SaaS tools in the French construction ecosystem.
The product was recognized for its clarity, efficiency, and visual quality, which directly contributed to its acquisition by Once For All in 2024.
Post-acquisition, the Batis console design system served as a core foundation for Once For All’s unified product suite, now powering 10+ enterprise modules across Europe.
