Banking Mobile Application
Project Overview
SecureBank Financial, a regional bank with $5B in assets and 300,000 customers, faced increasing customer dissatisfaction with their outdated mobile experience. Their existing app had poor ratings (2.1/5 stars), high abandonment rates, and was failing to meet the expectations of their increasingly digital-first customer base. They approached us to develop a modern, secure, and feature-rich mobile banking application that would improve customer satisfaction, increase digital engagement, and reduce operational costs through self-service capabilities.
Challenges
- Stringent security and compliance requirements (PCI-DSS, GDPR, SOC2)
- Complex integration with legacy core banking systems (30+ year old COBOL mainframe)
- Need for offline functionality for certain features
- High performance expectations from users
- Multi-device support with consistent experience
Our Approach
Security & Compliance
Security was our top priority throughout development:
- Implemented NIST-compliant biometric authentication (fingerprint and face recognition)
- Developed end-to-end encryption for all data transmission using AES-256
- Created secure storage solutions with hardware-level encryption
- Implemented certificate pinning to prevent MITM attacks
- Conducted regular security audits and penetration testing with HackerOne
- Built comprehensive audit logging for regulatory compliance
User Experience Design
We created an intuitive interface that simplified complex banking tasks:
- Conducted 15 user research sessions with diverse customer segments
- Created detailed user personas and journey maps for key banking scenarios
- Developed a custom design system with 60+ banking-specific components
- Built an accessibility-first interface meeting WCAG 2.1 AA standards
- Implemented dark mode and personalization options
- Created intuitive onboarding flows with 40% fewer steps than industry average
Technical Implementation
We built a robust application using modern technologies:
- React Native for cross-platform development with 98% code sharing
- TypeScript for type safety and code quality
- Redux for state management with middleware for offline support
- Node.js backend with microservices architecture
- MongoDB for flexible data modeling and high performance
- Custom middleware for legacy system integration
- Real-time notifications using Firebase Cloud Messaging
- Analytics implementation with privacy-first approach
Features

The application launched to overwhelmingly positive feedback and delivered significant business impact:
