Mobile Application Development

Next-Gen Fintech App and Digital Wallet

A growing fintech startup needed a consumer-facing mobile application capable of executing instant peer-to-peer transfers with bank-level security protocols.

Context

The Challenge

The startup had a functional backend but no mobile presence. They required a cross-platform application (iOS and Android) that felt entirely native, with incredibly smooth 60fps animations. Most critically, the architecture demanded military-grade encryption for local data storage, biometric authentication, and a real-time websocket connection to their core banking ledger.

Execution

The Fattah Solution

Fattah developed the application using React Native to ensure a unified codebase without sacrificing native performance. We implemented secure enclave integration for biometric unlocking and AES-256 local encrypted storage for session tokens. The UI was meticulously crafted with micro-interactions, while the network layer utilized optimized WebSockets for instant transaction state updates.
