Client Overview

Evergreen is an established dating platform specifically designed for users over the age of 50. While they had a successful web platform, their mobile apps were outdated, slow, and lacked modern features. To combat growing competition and meet the expectations of their increasingly tech-savvy user base, they needed a complete mobile app overhaul and a backend modernization to support their next phase of growth. They required a partner with proven experience in both legacy system modernization and building high-performance mobile applications.

Problem

Evergreen's existing mobile apps were built on an obsolete cross-platform framework, leading to poor performance, frequent crashes, and an inability to add new features. Their monolithic backend was struggling to handle peak loads and was difficult to maintain and update, hindering their ability to innovate.

Key Challenges

Zero-Downtime Migration:

Modernizing the backend and migrating user data without disrupting the service for their existing, active user base.

Intuitive UI/UX for a Mature Audience:

Designing a user interface that was clean, highly intuitive, and accessible for users who may not be digital natives.

Native Performance:

Building new, high-performance native apps for iOS and Android to provide a fluid and responsive user experience.

Enhanced Security:

Integrating modern security and verification features to protect their users from scams and fraud, a key concern for their demographic.

Our Solution

We proposed a two-pronged approach. A "Legacy App Rescue" POD focused on modernizing the backend, while a separate ".NET Modernisation Pod" and "Native Mobile Excellence" PODs worked in parallel on the new applications.

🔄 Backend Modernization

We re-architected their monolithic .NET backend into a cloud-native microservices architecture running on Azure. We used a phased data migration strategy to ensure a seamless transition with zero downtime.

🎨 UX/UI Overhaul

Our UI/UX Design Studio conducted extensive user research with Evergreen's target demographic to create a design system focused on clarity, large fonts, high-contrast visuals, and simple navigation.

📱 Native App Development

We developed two brand-new native apps from scratch: one in Swift for iOS and one in Kotlin for Android. This ensured the best possible performance, reliability, and integration with device-specific features.

🛡️ Advanced Safety Features

We implemented a multi-factor verification system, AI-powered suspicious message detection, and an easy-to-use "Report & Block" system to significantly enhance user safety.

Implementation and Execution

Backend Phase (Months 1-6)

The backend team focused on building the new microservices architecture and setting up the Azure infrastructure.

Design Phase (Months 1-2)

The UI/UX team conducted research, created wireframes, and delivered a complete design prototype for the new apps.

Mobile Dev Phase (Months 3-8)

The native iOS and Android teams built the applications based on the new design, connecting to the modernized backend APIs.

Data Migration (Month 7)

A carefully planned, multi-stage data migration was executed over a weekend during off-peak hours.

Beta Testing (Month 9)

A closed beta was run with a segment of Evergreen's power users to gather feedback and identify bugs.

The new apps were released to the app stores, with a phased rollout to monitor performance and stability before a full marketing launch.
