The Outcome

The Challenge

The mobile platform required deep architectural changes while maintaining a consistent experience for active guests using the application daily.

Legacy Architecture Causing Performance Degradation

‍The existing React Native bridge introduced UI lag, slower rendering, and serialization overhead that affected complex screens and animations, directly impacting how guests experienced the platform.

Fragmented APIs and Tight Backend Coupling

‍Multiple REST endpoints and direct Salesforce connections caused data over-fetching, increased latency, and made backend changes costly to coordinate, slowing feature delivery and reducing system dependability.

The Solution

We designed and delivered a phased modernization across both the mobile layer and backend connection stack to resolve performance and growth constraints.

React Native New Architecture Migration

‍Transitioned from the legacy bridge to the new architecture using TurboModules and Fabric Renderer, allowing synchronous communication and smoother UI performance.

GraphQL Unified API Gateway

‍Replaced fragmented REST endpoints with a single GraphQL layer to consolidate data fetching and reduce frontend complexity.

Salesforce Connection via GraphQL

‍Removed direct frontend Salesforce calls by routing all requests through the GraphQL layer with caching and rate-limit controls.

Microservices Coordination

‍Aggregated responses from multiple backend microservices through GraphQL, simplifying frontend consumption and improving long-term maintainability.

Observability and Monitoring

‍Built improved debugging and performance monitoring across services to support faster issue resolution and sustained system stability.

The Outcome

The resort platform now delivers a faster, more dependable guest experience backed by a modern architecture built for continuous development and backend flexibility.

45% improvement in app rendering speed and UI responsiveness after migrating to the React Native new architecture with TurboModules and Fabric Renderer.

35% reduction in API latency by replacing multiple REST endpoints with a unified GraphQL gateway that removed data over-fetching and backend coupling.

50% faster feature delivery cycles achieved through decoupled microservices and a centralized API layer that removed cross-team coordination bottlenecks.

We have been working with Entrans for the last two years and they have played a key role in building our solution. Their expertise and professionalism were evident throughout the development cycle, and we were very pleased with the final product. They have shown enormous skill and vast domain knowledge and their IT expertise is reliable and trustworthy. We would recommend Entrans for anyone looking for quality IT services, delivered in a professional manner
