Ellis

The Challenge

Ellis, a US startup serving immigrants, students, and H-1B holders with mobile/SIM and banking services, had done the hard part: validated their product with a working MVP. But the frontend was showing its limits - inconsistent UX, accumulated technical debt, and velocity constraints that would block the next stage of growth.

They needed staff-level frontend expertise to modernize the codebase without slowing the team's shipping pace.

What We Built

This engagement predates Arx Modus as a bureau: our founder joined Ellis's team directly, working in close partnership with the CTO to modernize the frontend over six months:

• Modernized architecture, bringing structure and reliability to an MVP-grade codebase
• Built out a shared component library, cutting duplication and speeding up feature work
• Established frontend standards for code quality, patterns, and practices

The focus was a foundation that would support the company's growth while still delivering visible improvements week to week.

Outcome

The modernized codebase reached release-ready state within the six-month window. The component library reduced duplication and accelerated feature development, and UX consistency improved across the product surface - leaving Ellis with a frontend foundation matched to their next phase of growth.
