Property Rental Provider

Building a Hybrid Platform, Without Rewrites

Summary:

Our client is one of the largest single-family rental home providers in the United States, managing tens of thousands of homes across dozens of states. The company serves a huge population of residents and relies heavily on digital tools to support leasing, maintenance requests, payments, and everyday property management.

They had already invested years into a modern React-based micro-frontend web platform; a sophisticated, modular system powering the majority of their resident-facing experience.

As they expanded their digital services to mobile, they initially believed they would need to rebuild everything from scratch, creating a full native mobile experience separate from the web. This would significantly increase cost, code duplication, long-term maintenance, and delivery timelines. T

hey approached gravity9 to help them find a smarter way, given our background in hybrid mobile architectures and complex frontend ecosystems, gravity9 was tasked with designing a future-proof mobile solution that balanced performance, reuse, and long-term sustainability.

Tech Stack:

Cross-platform Mobile: .NET MUAI
Web Micro-Frontends: React
Cloud Identity: Azure B2C /OpenID Connect
Native Integrations: Bluetooth + Smart-lock hardware
Core Languages: C#, .NET, TypeScript

Expanding a powerful web platform into mobile introduced significant architectural and maintainability challenges rather than simple development effort. The client needed to avoid duplicating features across web and mobile, integrate web micro-frontends into a native app at enterprise scale, maintain a single sign-on experience, and introduce device-level capabilities such as Bluetooth and smart-locks, all without sacrificing performance or long-term sustainability. Addressing these constraints required careful architecture validation and rapid prototyping before committing to full-scale delivery.

gravity9 adopted a structured, iterative approach, starting with discovery and a rapid prototype that proved web micro-frontends could run smoothly inside a native mobile shell. Iterative development then layered in native authentication, unified navigation, and device integrations through a secure communication bridge. The result is a proven hybrid architecture that protects the client’s existing web investment while enabling native mobile capabilities, faster releases, and simpler maintenance. Early client feedback praised the clarity of the architecture, the speed of delivery, and the ability to achieve a modern mobile experience without rewriting the entire frontend platform.
