Mobile App Development for FinTech

FinTech mobile apps handle money, which means security and reliability are table stakes. TechSaaS builds fintech mobile experiences with biometric authentication, encrypted local storage, certificate pinning, and secure API communication.

BizStreet pioneered WhatsApp-first financial services. We built the bridge between WhatsApp Business API and investor-facing dashboards, enabling a conversational funding experience that works on the device investors already use every day.

We build payment wallet interfaces with QR code scanning, UPI integration (for India), real-time transaction feeds, and balance management. Our payment expertise from HyperSwitch integration ensures robust, multi-processor payment handling.

For investment and portfolio apps, we build real-time data feeds using WebSocket connections, interactive charts for portfolio visualization, and push notification systems for price alerts and trade confirmations.
