FAQ
Can you integrate a payment gateway into an existing fintech app or wallet app?
Yes. I can implement payment gateway and payment integration using REST APIs, webhooks and provider SDKs, including transaction handling, status updates, validation and error management.
How do you design the wallet ledger for money transfer transactions?
I structure wallet transactions with proper debit, credit, balance validation and transaction history logic. The architecture can support P2P payment app flows while maintaining consistent transaction records.
Can you integrate KYC and secure authentication into a digital wallet?
Yes. I can integrate KYC workflows with secure authentication, 2FA and biometric login where supported. The implementation can include verification states, user access controls and secure API communication.
Can you build a money transfer app with P2P payment functionality?
Yes. I can develop P2P payment app functionality with sender and recipient validation, wallet balances, transaction history, transfer status, notifications and payment API integration.
What APIs can you integrate with a payment app or mobile banking app?
I can integrate REST APIs, payment APIs, banking APIs and third-party financial services. The exact integration depends on your provider, required endpoints, authentication method and transaction workflow.
Can you connect Stripe or PayPal to a fintech app and digital wallet?
Yes. Stripe, PayPal and other supported gateways can be connected through their APIs or SDKs. I can handle payment creation, verification, webhooks, transaction status and error handling.
Can you develop a crypto wallet app or neobank app with an admin dashboard?
Yes. I can develop the required wallet or neobank app architecture with authentication, transaction management, API integrations, user controls and an admin dashboard based on your technical requirements.
How do you secure API integration and financial transactions?
I use authenticated API requests, server-side validation, secure credential handling, access controls and webhook verification. Sensitive operations should remain server-side rather than exposing private keys in the mobile app.
Can the fintech app support transaction history and payment status tracking?
Yes. Transaction records can include amounts, references, timestamps, sender or recipient data, payment status and transfer states. The exact structure depends on the payment gateway and backend architecture.
What technology stack do you use for fintech and wallet app development?
I use Flutter or React Native for mobile development, with Node.js, Firebase or Supabase for backend services where appropriate. I also use REST API, Postman, GitHub, Figma, Stripe and PayPal for relevant projects.
