THE EXISTING PRODUCT
Complete UI/UX overhaul without disrupting existing users
Successfully redesigned and migrated a Ruby on Rails application to a new front-end while maintaining zero downtime and preserving full functionality for existing mobile app users. The gradual migration approach resulted in 20% increase in daily signups and 30% revenue growth.
Modernize an old Rails app while preserving the backend, mobile API, and existing service. A gradual interface rollout let the business improve conversions without an unnecessary application rewrite.
THE BUSINESS CHALLENGE
Zero-Risk Redesign Strategy
We adopted the existing back-end for the new design and built a completely new front-end, seamlessly integrating it with the updated back-end architecture. All changes were implemented with zero downtime and no risks to the business or existing mobile app users. We implemented a gradual user migration system with the ability to switch back to the old UI in case of any issues, ensuring complete risk mitigation.
The existing Ruby on Rails application had an outdated user interface that was affecting user engagement and conversion rates, but a complete redesign posed significant risks to business continuity and existing mobile app functionality.
THE WORK WE DELIVERED
Improve the product. Keep the business moving
- 01
Introduce the new interface gradually
We implemented a sophisticated dual-interface system that allowed us to gradually migrate users to the new design while maintaining the old interface as a fallback option. The new front-end was built using modern technologies and seamlessly integrated with the existing Ruby on Rails back-end. We ensured that all existing API endpoints remained functional for the mobile app, preventing any disruption to mobile users.
- 02
Validate the transition with users
The migration strategy included comprehensive testing, user feedback collection, and real-time monitoring to ensure optimal performance. Users could easily switch between the old and new interfaces during the transition period, providing maximum flexibility and risk mitigation.

VALUE FOR THE BUSINESS
Ruby on Rails App Redesign: the results
The redesign was completed with zero downtime and no disruption to existing services. We achieved a 20% increase in daily new user signups and a 30% increase in revenue. The gradual migration approach ensured that all existing mobile app users continued to have uninterrupted service throughout the entire process.
