Mobile Banking Application with Biometric Security

Secure, feature-rich banking experiences with real-time transactions and compliance-ready architecture.

The summary

A financial services partner engaged CoderVu to rebuild a consumer banking app with modern UX, biometric authentication, and real-time transaction processing — while meeting strict security and audit requirements.

The challenge

The legacy app suffered from slow transfers, poor onboarding completion, and security reviews that blocked feature releases. The client needed React Native delivery for iOS and Android, PCI-aware integrations, and observability that satisfied regulators and internal risk teams.

Team Size: 5 specialists
Engagement Length: 8 months
Engagement Model: End-to-end product development

The Solution

We delivered a React Native client backed by Node.js services, MongoDB for flexible account data, and Firebase for push and remote config. Biometric flows, fraud signals, and encrypted storage were implemented with security review checkpoints at each milestone.

“Our customers notice the difference — faster transfers, smoother onboarding, and a app they trust with biometric login.”
Head of Digital, Banking Partner

The outcome

The app reached 100K+ users with a 4.8/5 store rating within eight months. Transaction success rates improved materially, and release cadence accelerated after the new CI/CD and monitoring stack went live.
