Built quietly, built to last

As La Haus scaled rapidly across two countries, reaching 200+ engineers, 20+ designers, and over 1.6M users, the need for a unified and scalable design system became undeniable. I played a key role in shaping what would become Roomie our design system built not just to scale, but to evolve.

Process & Strategy

We restructured the system from the ground up: organizing files, defining versioning rules, improving governance, and aligning the process with how teams actually build and ship product.

Visual Language

We introduced scalable tokens and typographic styles to support brand flexibility. It wasn’t a rebrand, just a smarter, more accessible way to use our visual identity across products.

Component Architecture

We designed components to evolve not just ship. Using slot-based structures and simplified layer logic, we reduced complexity and mirrored code logic for seamless designer-dev handoff.

Documentation lived inside the system, directly linked to our dev repo. Components were easier to use, easier to trust, and fully integrated into how designers and developers work.

Adoption & Culture

We branded the system as a creative companion "Roomie" and built internal momentum with swag, training, and support. The system became a tool teams wanted to use.

"We created a friendly image to show the DS as a vehicle to create, rather than a blocker of creativity."

The outcome

Roomie achieved 100% adoption across all products, saved thousands in design/dev effort, and got a 90 NPS from designers. It proved that a well-built system isn’t a constraint it’s a catalyst.
