About FinEdge
FinEdge is a fintech startup established to provide accessible digital banking and personal finance management services to underbanked populations in Southeast Asia.
The company's platform offers mobile-first savings accounts, instant peer-to-peer money transfers, bill payment services, and personal budgeting tools designed for users who conduct the majority of their financial activities through smartphones.
To maximize their reach across both Android and iOS users while managing development costs efficiently, FinEdge selected React Native as the foundation for their mobile application, enabling a single shared codebase to serve both platforms simultaneously.

- Cross-Platform Mobile Architecture
- Financial Security Implementation
- KYC and Compliance Workflow Development
- Financial Data Visualization
- Quality Assurance and Performance Optimisation
The Challenges
Every project starts with real problems. Here are the core challenges we tackled for this engagement.
FinEdge needed to launch on both Android and iOS simultaneously within a tight nine-month timeline.
Financial transaction security required multiple authentication layers and robust fraud detection integration.
The application had to deliver a native-quality user experience despite being built on a cross-platform framework.
Complex financial data visualizations needed to render smoothly across a wide variety of device screen sizes.
Regulatory compliance requirements in multiple jurisdictions needed to be addressed within the application architecture.
Core approach & deliverables
A breakdown of the core components built and delivered for this project.
Unified React Native Architecture
Markeltree structured the React Native codebase to maximize code reuse across iOS and Android while allowing platform-specific adjustments where necessary to maintain native-quality interactions. Navigation, state management, and API integration were implemented using well-established libraries to ensure long-term maintainability.
Multi-Layer Security Implementation
Financial applications demand uncompromising security standards. Markeltree implemented biometric authentication, PIN-based access controls, session timeout management, and end-to-end encryption for all transaction data. Integration with third-party fraud detection services provided real-time transaction monitoring and anomaly alerting.
Performance Optimisation for Financial UX
Despite the inherent challenges of cross-platform development, Markeltree achieved native-quality animations and interactions by leveraging the React Native Reanimated library and optimizing component rendering through careful state management. Transitions between screens were smooth and responsive across both platforms.
Financial Data Visualization
Personal finance management requires intuitive visual representation of spending patterns, savings progress, and transaction history. Markeltree implemented a suite of interactive charts and dashboards that helped users understand their financial behavior at a glance. Visualizations were optimized for both small and large screen formats.
Regulatory and Compliance Architecture
Working closely with FinEdge's compliance advisors, Markeltree structured the data handling and user verification workflows to align with applicable financial regulations across FinEdge's target markets. KYC onboarding flows, document verification integrations, and audit trail functionality were built into the core platform.
Key Outcomes & Impact
Simultaneous iOS and Android launch achieved within the nine-month project timeline.
Shared codebase delivering significant cost savings over dual native development.
Multi-layer security architecture including biometrics, encryption, and fraud detection integration.
KYC-compliant onboarding workflows supporting multi-jurisdiction regulatory requirements.
50,000+ registered users onboarded within six months of launch.
Series A funding secured based on platform quality and demonstrated user adoption.
Choosing React Native was a strategic decision for us, and Markeltree was the ideal partner to execute it. They built an application that genuinely feels native on both platforms, which was something we were initially uncertain was achievable. The security architecture they implemented gave us and our users complete confidence from day one.
