Frequently Asked Questions

Can you integrate payment gateways in Flutter apps?
Yes. I have integrated Razorpay, Stripe, PayU, and UPI (via PhonePe/GPay SDKs) in Flutter apps. I handle the full flow: payment initiation, webhooks, receipt generation, refunds, and transaction history with proper error handling.
How do you ensure security in fintech apps?
I implement multi-layer security: biometric authentication, SSL pinning, encrypted local storage, root/jailbreak detection, anti-screenshot policies, session management with auto-timeout, and obfuscation. All financial data is encrypted using AES-256.
Do you have experience with KYC/AML systems?
Yes. At iBind Systems, I built KYC verification flows including document upload, OCR-based data extraction, liveness detection, and integration with third-party verification APIs. The system processed thousands of verifications daily.
Can Flutter handle complex financial calculations and charts?
Absolutely. Flutter handles real-time chart rendering (fl_chart, syncfusion), complex calculations, and large dataset visualization efficiently. I've built real-time portfolio trackers and transaction dashboards with smooth 60fps performance.
